摘　　要：对基坑开挖对既有建筑物的影响进行分析,以某办公楼项目为例,结合案例的实际情况,进行基坑开挖后位移数值的有限元模拟分析,并对基坑开挖后既有建筑物产生的不均匀沉降与受力等进行系统性的分析,最终形成基坑开挖对既有建筑影响的评价。The impact of foundation pit excavation on existing buildings is analyzed.Taking an office building project as an example,combined with the actual situation of the case,the finite element simulation analysis of the displacement value after foundation pit excavation is proposed,and the uneven settlement and stress of existing buildings after foundation pit excavation are systematically analyzed.Finally,the influence of foundation pit excavation on existing buildings is formed.

关 键 词：基坑开挖 既有建筑物 不均匀沉降 不均匀受力
