摘　　要：研究以下穿居民区的地铁线路隧道为工程背景,利用midas GTX-NX软件进行了有限元模拟,分析了隧道施工对厂房的扰动影响,并提出了分离式隧道下穿建筑物的沉降变形有限元研究。研究表明:隧道施工结束后,隧道上部土层沉降量在深度上呈现逐渐增大的趋势,随着与隧道轴线距离的减小,地面沉降逐渐增大,其与采用数值模拟方法计算出的侧向下沉趋势与经验公式方法是一致的。Taking the subway tunnel passing through residential areas as the engineering background,midas GTX-NX software was used for finite element simulation to analyze the disturbance of tunnel construction on the factory building,and a finite element study on the settlement deformation of separated tunnels passing through buildings was proposed.Research has shown that after the completion of tunnel construction,the settlement of the soil layer in the upper part of the tunnel gradually increases in depth.As the distance from the tunnel axis decreases,the ground settlement gradually increases.It is consistent with the lateral subsidence trend calculated using numerical simulation methods and empirical formula methods.
