THE FINITE ELEMENT METHOD FOR EVALUATING THE REINFORCEMENT OF ROCK SLOPE

With the development of the computer science,many numerical calculating methods are used for slope stability analysis.The finite element method is one mature numerical method,and can analyze the slope stability.In this paper,the linear elastic finite element method is used for the stability of one rock slope in southern Zhejiang.The contour map of the maximal and minimal principle stress,the stress vector graph and the contour map of principle stress difference have been gotten after calculating.These maps are used to analyze the slope stress.The same method is used to calculate and analyze the slope stress when the slope is reinforced.This paper compares these two different stresses,and evaluates the stability of slope and the reinforcing design.
