Abstract

With the rapid development of China's economy, the pace of China's integration into the global economy is also growing fast. The pace of industrialization in China is rare in the world of speed forward, and therefore need to build a large number of civil engineering, has been widely used in order to ensure the implementation of various projects, a lot of the retaining structure. The retaining wall is a retaining structure to prevent the collapse of the soil is an important form of retaining structures. Gravity retaining wall due to its use of local materials, simple construction, high rigidity, low-cost advantages, the most widely used. Gravity retaining wall applications is very wide, but the calculation process is very complicated. At present, most of them are still using hand calculations and look-up table or directly apply to the calculation of the design of retaining walls retaining wall standard atlas, a lot of work, and can not be the flexibility to choose the type and cross-section of retaining walls, therefore, to develop a Case gravity retaining wall calculation software is very necessary. In many programming languages, Visual Basic 2008 completely object-oriented programming techniques for the development of Windows applications, Web applications provide the fastest and most simple method. It is not only a powerful and easy to learn, and the fully compatible Windows7/XP/Vista operating system, it is suitable for software development, and is widely used. This paper first discusses the Coulomb active earth pressure coefficient, Rankine active earth pressure coefficient as well as the architectural foundation design specification \pressure coefficient Ka impact parameter commonly used expression analysis derived parameters affect the size; then compared using MATLAB active earth pressure coefficient used in accordance with Appendix L of the Building Foundation Design Code \active earth pressure coefficient calculated active earth pressure and the specification does not consider the impact of uniformly distributed load, uniformly distributed load are translated into the size of the difference between the soil thickness calculated active earth pressure both; using MATLAB compare the cohesive backfill active earth pressure Rankine conditions commonly used formula to calculate the active earth pressure and with \size of the difference between the soil active earth pressure both; Finally, according to the foundation, retaining walls related specifications, procedures, Atlas, and some references to analyze the process of calculation of gravity retaining wall design, the retaining The calculation of the wall formulaic, and then use the Visual Basic 2008 programming, developed a relatively complete set of gravity retaining wall calculation software. The software covers the various forms of the retaining wall of a variety of conditions, the design process is clear and easy to understand, highly versatile, easy majority of designers use. The software can be replaced by computer designers a lot of calculations and checking the designers simply based on the calculation results of the computer section modify and resize, which can significantly improve the work efficiency.
