Numerical analysis of surface settlement induced by shield tunnel construction of adjacent structure
摘要
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.关键词
