Stability Analysis Based on a Highway Slope in Yunnan

This paper analyses the stability of a highway slope in Yunnan by using the FLAC3D numerical software. To simulate the stability coefficient only considering the gravity loads and also taking into account the action of groundwater and then in comparison with the result calculated by the limit equilibrium method consider the influence of groundwater , the results show that the slope in a state of instability with the effect of groundwater. Then use anchorage to upgrade the slope, and the slope in a stable state after reinforcement. The simulation results have certain reference significance to the slope management.
