摘　　要：深基坑的三边是预留岩埂作的围堰,另一边为超高边坡。省道位于超高边坡上,施工过程中不能中断行车。施工时,超高边坡发生二次较大的滑坡,时间间隔8个月,经对滑坡体进行钻孔取样分析,该滑坡体为古滑坡体,是土石混合料。根据现场情况,先后采取降坡比、框格梁、预应力锚索、锚索抗滑桩等措施进行处理,保证了边坡和基坑的稳定。The three sides of a deep foundation pit are cofferdams made of reserved rock ridges, and the other side is an ultra-high slope. As the provincial road is located on the slope, the traffic cannot be interrupted during the construction. While two large landslides of the ultra-high slope occurred during the construction with the time interval of 8 months. Borehole sampling analysis of the landslide mass shows that it is an ancient earth-rock mixture landslide mass. Considering the practical in-situ situations, treatment measures such as the slope ratio reduction, frame beam, pre-stressed anchor cable, anti-slide anchor cable pile are taken, which ensure the stability of the slope and the foundation pit.
