摘　　要：基坑工程施工过程中边坡失稳,引起相邻住宅楼业主的担心。为了解边坡失稳对临近建筑物的影响,为工程下阶段建设提供依据,对建筑物主体工程和失稳后的边坡及楼现状进行了检测,并对边坡失稳可能存在的影响进行了分析计算。结果表明:1)基坑北侧边坡失稳,致使楼南侧东单元后浇楼梯损毁;2)楼主体结构未因基坑边坡失稳坍塌而受到损害;3)在最不利组合工况下,边坡滑裂面在楼基础以上,对楼基础以下地基未形成扰动。The Slope instability in the process of foundation pit engineering construction can affect the safety of adjacent buildings. Based on the detection of the current situation of a building main project and the slope after failure, the influence of the slope failure on the adjacent buildings is analyzed, and the results show： 1）Slope instability in the north side of the foundation pit, resulting in the stairs, which is after pouring, of the East unit on the south side of the building damaged;2）The main structure of the building is not damaged due to the instability of foundation pit slope;3）Under the most unfavorable combination condition, the sliding surface of the slope is above the bottom of the building, and the bearing strata is not disturbed.
