Numerical simulation and analysis of high rock slope based on the finite element method

The stability of high rock slope is very important to the safety of its lower building and industrial site.Simulation and analysis on failure mechanism of rock slope by finite element strength reduction method is an effective way of analysis on reliable stability of rock slope.In this study,finite element stress analysis method which combined with strength reduction theory was used to numerically simulate excavation and support processes in west slope of Baiquan Iron ore mine,and can scientifically analyze mechanism of deformation and failure and evolution process of slope.This is a more practical method in which interaction of supporting and retaining structure such as anchor etc.and the effect of groundwater are synthetically considered,and can verify rationality of slope reinforcement measures.The physics and mechanics index of soil and rock accorded in simulating and analyzing on stability of slope are from engineering geological investigation report and more reliable,and the analysis result is practicable.The analysis result of slope stability can be applied to guide directly strengthening design of slope,to adjust size and layout of anchors in according with stress condition of rock slope,to make reinforcement measures of slope to be more safe,reliable,economic and reasonable.
