Stability Analysis of a Reinforced Soil Slope Based on the Strength Reduction Method

Abstract:

Apply large general-purpose finite element analysis software ABAQUS as a platform, The criterion of iteration non-convergence conventionally used for assessing the instability state of slopes,and an example is given to the following conclusions: The strength reduction method based on ABAQUS simulate anti-slide pile slope stability analysis that has a true reflection of the elastic-plastic deformation in geotechnical engineering,it can be widely used in elastic-plastic deformation problems in geotechnical engineering. The anti-slide pile can effectively improve the stability of slopes, setting up anti-slide pile egitimately in the soil plays an important role at the safety of slope stability.
