The Analysis Of Anti-slide Pile Support Slope With Strength Reduction Method

This paper summarizes the application of strength reduction factor method in the anti-slide Pile support slope. It summarizes the development and the research present situation of anti-slide Pile support slope,and point out a number of problems in the design and calculate method. Described the development process of strength reduction method, briefly introduced the basic principles of FLAC3D software and its features. analyze and compare the several existing instability criteria,and established models to analysis the above several instability criterion and compare the result. The conclusion is that use non-convergence method to calculate safety factor of anti-slide Pile support slope is feasible.Establish the finite element model of slope and anti-slide pile. this paper adopts pile unit which FLAC3D provide to numerical simulation anti-slide pile,analysis the action principle,and discuss the parameters valve of tangential coupled spring and normal direction coupled spring.To ansysis anti-slide pile support slope using safety factor as a reference indicator. Optimization analysis anti-slide pile parameters,such as pile situation,pile distants,pile anchorage length,and to obtain reasonable and economic support plan. In the last it discuss the soil arching effect in the piles,and obtain reasonable pile space basis on soil arching effect.
