摘要
通过对该挖方滑坡的地质条件、岩土体结构、软弱结构面特征、变形特征及监测数据的分析,并采用FLAC3D进行数值模拟,探讨川东北红层地区软弱夹层岩体边坡的破坏机制,为类似条件边坡的开挖、监测、预警和支护提供参考。
The landslide was caused by excavation engineering. The failure mechanism is explored for slopes with soft interlayer in the red rock area of Northeast Sichuan through the analysis of the landslide＇s geological conditions, rock and soil structure, soft structural surface, deformation and the monitoring data. The study provides a reference for the excavation, monito- ring, warning and bracing of the slope with similar conditions.
