| 摘 要： | 在建筑物密集的城区，盾构施工使周围一定范围内的既有建筑物受到影响。在考虑建筑物基础形式的不同的情况下，采用二维有限元方法对邻近不同位置建筑物工况下的盾构隧道施工进行了模拟和分析。研究表明，建筑物轴线到隧道轴线的水平距离和建筑物基础形式是影响邻近建筑物工况下隧道开挖引起地面沉降的重要因素，建筑物的存在会增大隧道开挖引起的地面沉降，建筑物对隧道开挖引起的地面沉降的影响存在一个影响范围，超过该范围时建筑物的影响可忽略不计

| Abstract: | In the area with dense and intensive buildings, the construction of shield tunnel will influence the subsiding of adjacent building. In view of the structure's different foundations, 2D FEM is adopted to study and simulate the shield tunnel construction of adjacent structure. It is indicated as follows: the level distance from tunnel axis to building axis and different foundations are the important factors that influence surface settlement induced by shield tunnel construction; surface settlement is increased by the existence of building with tunnel excavation construction. Exceeding the ranges that surface settlement induced by shield tunnel construction, effecting of structure can be neglected. |
