基于离散元的岩质高边坡开挖支护数值模拟
Numerical Simulation of High Rock Slope Support Under Excavation Based on Discrete Element Method
摘要
Abstract
In order to analyze the impact of excavation and support of high rock cutting slopes on the stability of slope,the two conditions were compared between excavation without support and timely supported by bolt.The effect of bolt support was evaluated through the method of combining discrete element numerical simulation with field monitoring.The results showed that the vertical displacement caused by excavation was mainly concentrated in the middle of the excavation face.Under the same excavation conditions,the maximum value of the slope excavation face space-facing horizontal displacement was reduced by 2.50 cm,and the safety factor of cutting slope was increased by 8.62%,indicating that the slope was in a basically stable state.In addition,the validity and correctness of the numerical simulation results were verified by comparing with the field monitoring data,which indicated the applicability of the discrete element method for analyzing the stability of rocky slope.关键词
