FAST景区公路滑塌式危岩稳定性分析及防治对策

本文以FAST景区公路上的两处滑塌式危岩体A和危岩体B为研究对象,运用极限平衡理论分析了滑塌式危岩在不同荷载组合类型作用下的稳定性。计算结果表明,三种荷载组合下的危岩体A、B均处稳定状态,但暴雨和地震力作用下稳定性状态稍差。极限平衡法对FAST景区公路危岩体的稳定性分析具有实用价值,相关研究结论有助于FAST景区公路滑塌式危岩体的灾害防治。

In this paper,two potentially collapsed dangerous rock mass A and B on the highway of FAST scenic spot were taken as research objects,and their stability under different load combinations were analyzed by using limit equilibrium theory.The calculation results showed that the dangerous rock mass A and B are in stable state under the three load combinations,but the stability state is slightly worse under the action of heavy rain and seismic force.The limit equilibrium method is of practical value for the stability analysis of the highway dangerous rock mass in FAST scenic spot.
