Program Of Slope Supporting And Stability Analysis Of Railway

Design of Retaining structure is very important for the engineering. manual calculation has been unable to meet the needs of the present design work and it can not achieve the perfect purpose. However, with the help of computers, we can design better and faster and save investment. In this paper, we explore the program of slope supporring and stability analysis combine with "The research of Yumeng railway".In this paper, the following work were done:1. Summarizing the relevant theory of retaining structures and slope stability analysis which as the basis for program.2. The paper has three programs, which are retaining wall procedure, slide-resistant pile procedure, slope stability analysis procedure.3. Retaining wall procedure has achieved designs of which are gravity road shoulder wall, gravity road embankment wall, balance weight retaining wall and gravity cut slope wall. This procedure can according to different wall-type parameters, load parameters and soil parameters automatically identify the most reasonable of the most economical wall width. And it is suitable for the design and calculation of retaining walls of single line double line in general areas, the earthquake region and soggy region. Except for the design of retaining wall of the railway , this procedure can be used to design road and other loads by dealing with the conversion earth column differently. Therefore, as long as modify the procedure a little it can be used for roads, water conservancy, housing construction and other departments.4. Slide-resistant pile program has realized these fuctions which are given slip surface count internal friction angle, given the shape of sliding surface design calculation, given the landslide thrust design calculation of landslide, given sliding surface moment, shear force design calculation.5. Slope stability analysis procedure is composed of two modules. The Slope stability analysis program has realized these fuctions which are fellenius in fees and consolidation of the law of effective stress analysis and calculation of slope stability, based on Terzaghi' s consolidation theory to the three degrees of consolidation and the calculation based on the layerwise summation method of settlement calculation.6. The development of this procedure uses object-oriented method as the theoretical foundation in the Windows XP system, which is developed using Visual C ++ 6.0 as the programming development tools. it provides users with a friendly and convenient man-machine interface data input environment, and it' s easy to operate, the interface has more optimization. The program has achieved to enter and modify the relevant parameters in the interface, and the data of the interface can be automatically saved and the calculated result is automatically imported to Excel spreadsheet that is in favor of extraction of data and design of standard diagram.
