توضیحات:
SHAFT is used to compute the axial capacity and the short-term, load versus settlement curves of drilled shafts in various types of soils. SHAFT v5.0 can analyze drilled-shaft response in six types of strata: i) clay - cohesive geomaterial, ii) sand - cohesionless geomaterial, iii) clay-shale, iv) strong rock, v) gravel - cohesionless IGM, and vi) weak rock - cohesive IGM. The program allows for any combination of soil layers to be placed in a layered profile.

SHAFT features an approach known as concurrent engineering, where input, processing, and graphical output are performed from a single environment. An additional simple text-file, containing the complete output listing, is also computed in every computer run.

The analytical methods employed by SHAFT are based on experimental data obtained from hundreds of well-instrumented load tests of full-sized drilled shafts. New criteria for soil response of gravel and weak rock were modeled after papers of recent publication.

In general, most of the analytical methods used by SHAFT are based on suggestions from the latest FHWA manual Drilled Shafts: Construction Procedures and Design Methods by L. C. Reese and M. W. O’Neill, published in November of 1999. This manual was produced under sponsorship and contract from the Federal Highway Administration (FHWA) and is distributed by the International Association of Foundation Drilling Contractors.

LIST OF FEATURES
SHAFT allows users to investigate capacities of drilled shafts of different diameters thus helping on the selection of most economical sizing. The new SHAFT v5.0 extends this option of multiple diameters to drilled shafts socketed into weak rock or gravel.
The program features a second-generation, windows-based module that combines in a single interface the input of data, the processing of mathematical computations, and the graphical display of information contained in the output file.
The program analyzes straight as well as belled shafts.
The new SHAFT v5.0 can analyze drilled shafts or grouted piles with diameters smaller than 12 inches.
Separate factors of safety may be specified by the user for side resistance and for end bearing. The new SHAFT v5.0 now graphs output results based on Ultimate and/or Factored loadings.
The user may manually input lengths of shaft at the top and/or bottom with neglected friction of resistance in order to account for possible moisture change or for other factors noted in the user manual.
SHAFT allows for the computation of soil resistance to uplift forces. The program can use any reduction factor specified by the user for friction of transfer in uplift of straight shafts.
The program produces tables of values or graphs, as a function of depth, for a variety of soil profiles, showing capacities in side resistance and in end bearing, along with the sum of the two. The theoretical volume of concrete is also shown for each depth.
A short-term, load-settlement curve may be computed for drilled shafts of a specific length.
Iterative techniques are employed in solving the nonlinear finite-difference equations.
The user manual of SHAFT v5.0 includes the latest equations recommended in FHWA manuals. The theory for the methods of analysis is fully presented, along with the recommended technical procedures. Example problems are supplied for reference. More than thirty additional technical references are listed to provide additional information on the methods employed in SHAFT.

* View the Shoring slideshow

SHORING Suite is a software package that contains 4 Modules: Shoring, EarthPres, Surcharge, and Heave. These modules are sophisticated design and analysis tools developed by experienced engineers and professors. The program has been widely used by engineers, contractors, universities, and government agencies nationwide and overseas. The program is flexible, powerful, and has high performance qualities.

Well Referenced: The calculation is based on Federal Highway Administration (FHWA) methods, US Navy DM-7 (NAVFAC) manual, the Steel Sheet Design manual (USS), and TRENCHING AND SHORING MANUAL of, California Department of Transportation. It can be used for complex ground conditions, surcharge loads, and many types of shoring walls including: braced cuts, cantilever walls, bulkhead walls, sheet pile walls, soldier piles & lagging systems, tangent pile walls, slurry walls, and any flexible walls. The program can link to EarthPres and Surcharge modules so that the data from these two programs can be directly imported into Shoring.

Great Tools: The program shows diagrams of pressures, shear, moment, and deflection. It calculates the moment of the piles and selects the five most suitable piles for you. The program not only presents the major properties of these piles but also calculates the top deflection of each pile. For braced systems, the program supports calculation for wale and strut. For tieback systems, the program can determine the free length, bound length, and non-load zone of tieback anchors. <Smart> places soil properties at your fingertips. It is great tool for shoring design engineers.

How does one input information to the SHORING programs?

Two types of input are commonly used for SHORING: soil pressure diagrams and parameters.

The pressure diagram input is based on the configuration of pressures on the wall. These diagrams are constructed by determining active pressure, passive pressure, surcharge pressure, and water pressure based on soil conditions, soil parameters, and surface loads. The pressure diagrams must be constructed by the user before inputting them to the program. Use of pressure diagrams for input allows maximum flexibility for handling differing field situations and wall configurations. Our SHORING program uses pressure diagram input. The graphical presentation in the programs provides an immediate visual representation of the pressure diagrams so they can be checked rapidly for accuracy.

Shoring Suite Plus also supports parameter input. For the soil parameter input, soil physical properties (such as friction, unit weight and cohesion) and wall configuration (e.g., water table, wall height, surcharge load) are entered. You have to use Epres to input the information, then Epres will generate the pressure diagram for the SHORING program. These two programs are tightly integrated for data translation.

What are the output results of the SHORING program?

The output from the SHORING program includes:

* Reaction force for each brace, or tieback force for each anchor.
* Minimum embedment for soldier piles or sheet piles.
* Shear forces and moment of the pile at each span (between braces) and the maximum moment. This allows selection of the pile section based on maximum moment.
* Diagrams of pressures, shear, moment and deflection.
* Optimum selection of pile/beam from database.

What does the EarthPres program do?

Since the SHORING program uses pressure diagram input, one must determine the active and passive pressures before they can be entered. For level surfaces or infinite slopes, active and passive pressures can be calculated easily using Rankin's or Columb's equations or charts. However, if the ground surface is irregular, (i.e. two or more stages of slope), the determination of soil pressure is difficult. Sometimes empirical methods or conservative assumptions are made to solve the problems. Epres searches the failure surface to accurately determine the active or passive pressures on a wall. Wall friction, wall buttresses, and a complex ground surface can be accounted for. Epres is a very useful tool for the SHORING program. The data from Epres can be automatically translated to SHORING.

What does the Surcharge program do?

If there are surcharge loads on the ground surface near the wall, they produce additional lateral pressures on the wall which must be considered in the analysis. Lpres can determine the lateral pressure on a wall caused by different types of surcharges: point loads, strip loads, area loads, or combinations of these loads. The results are output in the form of a pressure diagram. The program is very useful for the design of retaining or shoring walls, and is another very useful adjunct tool for the SHORING program. The data from Lpres can be automatically translated to SHORING.

Does the SHORING program require EarthPres and Surcharge?

Both Epres and Lpres are stand-alone programs, which can be used for many geotechnical and construction problems. The SHORING program does not require Epres and Lpres. Without the two programs, you have to construct all the pressures yourself and input them to SHORING. We recommend that you purchase these two programs with the SHORING program, as they will increase your capability to easily solve problems with complex situations.

حركت نسبي ناپيوستگي ها نيز با روابط خطي و يا غير خطي نيرو –جابجائي در امتداد عمودي يا برشي ناپيوستگي ها پوشش داده مي شود .UDEC داراي چند مدل رفتاري براي مواد دست نخورده و ناپيوستگي ها مي باشد كه مدلسازي ناپيوستگي ها را با شرايط موجود زمين شناسي وفق مي دهد.
UDEC براساس محاسبات لاگرانژين عمل مي كند كه براي تغيير شكلها و جابه جائييهاي بزرگ مورد استفاده قرار مي گيرد.اين نرم افزار با سرعت محاسبه بالا براي مدلهايي با چند هزار بلوك طراحي شده است و حل مسايل در آن با پيشرفت در پله هاي زماني صورت مي گيرد.
اين نرم افزار 950 كيلو بايت فضا اشغال كرده و تحت سيستم عامل
MS-DOS اجرا مي شود و حداقل به 4 مگابايت RAM براي اجرا نياز دارد .اين نرم افزار مدلي با بيش از 2500 بلوك صلب (1000 بلوك تغيير شكل پذير )را با 8 درجه آزادي براي هر بلوك در يك كامپيوتر شخصي با 4 مگابايت RAM حل مي كند .البته ورسيون جديد اين نرم افزار تحت 3DEC نيز موجود مي باشد كه توانايي حل مسايل تحليلي سه بعدي را نيز فراهم ساخته است.
قبل از آشنايي بيشتر با اين نرم افزار برخي از مزايا و معايب اين نرم افزار را بيان مي كنيم :
مزاياي برنامه UDEC را مي توان به صورت زير خلاصه كرد :
1-شبيه سازي مهندسي معمولا شامل مراحل طولاني از عمليات نظير تعيين تنش برجا،به كاربردن بارها،حفر تونلها ونصب نگهداري مي باشد. در برنامه UDEC يك سري از دستورات ورودي (از فايل ورودي يا صفحه كليد) كه با مراحل فيزيكي فوق انطباق دارد استفاده مي شود .
2- فايلهاي ورودي نوشتاري مفاهيم خوبي براي ثبت مدارك مربوط به يك تحليل در يك مساله مهندسي مي باشند .
3-فايل داده ها مي تواند به راحتي با يك ويرايشگر متن تهيه شود.
و چندين فايل داده را مي توان پشت سر هم جواب گرفت.
4-ساختمان با فرمان پيشرونده UDEC امكان ويرايش برنامه هاي خروجي و ورودي را بدون خروج از برنامه به استفاده كننده مي دهد.
5-با توجه به حل مساله در پله هاي زماني متوالي مي توان با وارد كردن زمان نتايج قابل توجهي به دست آورد .
از مشكلات و معايب اين نرم افزار مي توان به موارد زير اشاره كرد:
1-اين نرم افزار سيستم عامل MS-DOS اجرا مي شود و علاوه براين از نوع نرم افزار هاي Commond-line است و بر خلاف برخي نرم افزار ها مثل PHASES يا DIPS اين برنامه بدون منو مي باشد و ورسيون تحت ويندوز اين نرم افزار موجود نمي باشد،اين امر باعث شده كه كار با اين نرم افزار وقت گير باشد و نياز به تسلط بر فرامين اين نرم افزار براي كار با آن واجب است.
2- سرعت پايين محاسباتي اين نرم افزار به خصوص در محاسبات براي بلوكهاي تغير شكل پذير و در مدلهايي با بلوكهاي فراوان.(حل يك مساله با حدود 1000 بلوك صلب در يك و نيم ميليون سيكل حدود 4 تا 5 ساعت به طول مي انجامد)
3-گاهي اوقات در هنگام بروز مشكل اين برنامه به جاي صدور پيغام خطا به اصطلاح مي پرد يا از دور خارج مي شود.به عنو.ان مثال مي توان به مشكل همپوشاني (Overlap) بلوكها اشاره كرد.
4- عدم وجود خاصيت Autosave در اين نرم افزار باعث شده تا مشكلاتي در ذخيره محاسبات انجام شده ،در اثر قطع برق يا مشكلات خود برنامه به وجود آيد(دستور Save بايد براي ضبط محاسبات و تحليل ها به كار رود.)
فايل اجرايي اين نرم افزار UDEC.EXE نام دارد و داده ها واطلاعات ورودي بهتر است در يك ويرايشگر متن مثل notepad آماده شود و سپس با پسوند DAT ذخيره گردد تا به هنگام لزوم براي حل مساله فراخواني شود.
