摘要

严家坡料场滑坡是大规模切坡引发的大型滑坡,存在完整的周界和贯通的滑移带,具有推移—牵引的复式特征,勘查期间已处于极限平衡状态,威胁下方企业及住户的安全。在查明滑坡基本特征及成因机制的基础上,对该滑坡实施了中后部削坡减载+前缘填土压脚+截排水的应急抢险工程治理。反馈的信息表明,应急抢险工程使滑坡变形得到控制,对该滑坡整体稳定起到了积极作用。该滑坡应急抢险工程治理经验可供类似工程借鉴。
        The landslide of Yanjiapo quarry is a large scale landslide which has a complete boundary and a coherent sliding zone caused by largescale engineering excavation. It exhibits complex features with retrogressive and progressive landslide. The landslide was in the state of limit equilibrium. During the exploration. It threatened the safety of residents and enterprises in front of the landslide. On the basis of identifying the basic characteristics and the genetic mechanism of the landslide,geohazard emergency engineering which unload in the posterior part of the slope and backfill on the slope toe were implemented. The feedback information shows that the deformation of the landslide has been controlled after the geohazard emergency engineering,and the geohazard emergency engineering has played an big role in the overall stability of the landslide. The experience of geohazard emergency engineering of the landslide can be used for reference in similar projects.
