摘　　要：建筑岩质边坡影响着下方建筑物的安全,其变形破坏模式也非常复杂,本文以雅安市某殡仪馆岩质边坡为例,在详细的工程地质调查及勘查的基础上,查明了滑坡体所处的地质环境条件、边界、规模、形态特征及变形特征;该滑坡的形成因素是坡脚开挖、易滑地层及降雨,破坏模式为滑移—拉裂,通过分析滑坡原因,提出“旋挖桩+挡土墙+护角墙+截、排水沟+锚喷工程+削坡减载+清除转运堆积体”的综合治理方案进行应急抢险。Building rock slopes affect the safety of buildings below,and their deformation and failure modes are also very complex.This article takes a rock slope of a funeral home in Ya'an City as an example.Based on detailed engineering geological investigation and exploration,the geological environment conditions,boundaries,scale,morphological characteristics,and deformation characteristics of the landslide body are identified;The formation factors of the landslide are excavation at the foot of the slope,slippery strata,and rainfall,with a failure mode of sliding and tearing.By analyzing the causes of the landslide,a comprehensive management plan of"rotary excavation piles+retaining walls+corner walls+interception and drainage ditches+anchor spraying engineering+slope cutting and load reduction+removal and transportation of accumulated bodies"is proposed for emergency rescue.
