System Of Support Structure CAD And Database Of Slope

In China, Support technique of slope in geotechnical engineering develops quickly and sliding-resistant system has already been improved from self-weight type retaining wall to kinds of new and light ones. A large quantity of work is involved in the designing structure of sliding-resistant system. We need to anatomize the stability of slope before designing the supporting structure. Up to now, some specific software which can solve the problem have been turned up, they can only deal with the designing work within the last period of calculating and unable to provide alteratives and can't interact with the designer efficiently. We should select proper supporting systems according to the particular geotechnical conditions before starting our designing for the purposes of working on speedily and conveniently, prominent quantity of economic benefits and reliable quality. In order to reduce the designer's work we should make the best of the computer technology of speedy, accuracy and automation. For solving the above all problems we are making an attempt to develop a programs with varied methods of calculation for stability, kinds of alterative schemes according to the real requirement and rely on interrelated codes.This software is based mainly on Technical code for building slope engineering (GB50330-2002). It offers interface handle platform and flexible drawing blocks which is convenient to the designers. Computer Aided Design system includes design, analyses and calculation and drawing is formed. It can calculate the stability of slope and inner force of support structure, can draw inner force graphic of support structure, can analyze the pull of the support structure and arrange it, and can offer the code lists to be referred to. Further more, this software has a database system on slope through which you can browse, add, edit or cancel some slope information, which you can inquire into any necessities realtimely. Based on the principle of the foundation coefficient"m-m","m-k"and"k-k"method, the finite difference method is presented to analyze the internal forces of a anti-slide pile. The calculation and image processing are programmed. An example shows that the solution with high precision can be obtained if the segments are small enough although more computing time may be consumed. Obviously, the calculation precision is better than that of traditional method. The results of image processing by the program optimize the construction design of anti-slides piles. To calculate the internal force of draft bar of anchor breast wall, this paper adopts the displacement method instead of traditional three bending moment...
