摘要：The construction of underground project or the underground tunnel will influence the subsiding of neighboring building on the earth surface. In view of soil disturbance, 2D finite element method is adopted in this paper to study and shield tunnel construction of adjacent structures. Our research indicates that surface settlement together with force and deformation of the lining increase by the existence of buildings, simultaneously, additional stress and deformation of adjacent structure are induced during tunnel excavation construction. When L/D = 0.5 to 2, great surface settlement is produced with more settlement difference between building head and tail, and the building is in danger in the region. At the same time, the value of inner force also increases obviously. Out of the region, the influence on the buildings is ignored.
