摘　　要：随着城市隧道的修建,浅埋隧道穿越房屋的数量明显增多.应用三维有限元计算地面房屋横跨凹凸区的工况,得出了房屋不同区域部分与不同方向的变形规律,为隧道接近建筑物施工提供了参考价值.With the construction of urban tunnel,more and more shallow cover tunnels are passing through buildings.Applying three-dimensional finite element to calculate ground buildings which cross the hog and sag districts,the deformation regular of different regional parts of the building was obtained.These conclusions can be the valuable reference for the similar projects with tunnels close to buildings.

关 键 词：浅埋隧道 地面房屋 沉降槽 位置区域 变形情况
