英文摘要Large-scale excavation projects on high - steep rock slopes can potentially cause landslide disasters, especially if the faults are close to the slope's rear edge. This study uses field investigation and on-site monitoring to analyze the failure mechanism of rockslides with oblique intersecting faults caused by engineering excavation and rainfall. It examines how anti-slide piles and anchor cables affect rockslide stability during excavation, and proposes corresponding mitigation measures for slope - top platform collapse. The results show that engineering excavation is the main factor leading to the sliding of the Baihe rockslide. The fault fracture zone promotes the expansion of surface cracks on the landslide, providing an infiltration channel for rainwater, which leads to slow creep along the fault and sliding zone of the landslide. The hydraulic conductivity of the fault fracture zone causes collapse failure of the Baihe rockslide top platform under the condition of rainfall, and the addition of drainage channels and pipes effectively alleviates collapse failure. This study contributes to understanding the instability mechanism and deformation evolution process of high - steep rock slopes when faults are located at the rear edge of landslides. Moreover, the reinforcement measures proposed for the Baihe rockslide and mitigation measures for slope - top platform collapse have reference significance for large - scale excavation and treatment of high - steep rock slopes in mountainous regions.
