隧道施工中盾构机吊装对基坑支护结构稳定的影响
Influence of Shield Lifting on Supporting Structure of Pit During Tunnel Construction
摘要
Abstract
Shield lifting is an important procedure in tunnel construction by shield method.Due to the large size of shield,heavy load and short lifting time,lifting process becomes a big risk in shield tunnel construction.During the lifting process,the displacement of continuous wall,the axial forces and deformation of supports were monitored in real time.Finite element method(FEM) was applied because the lifting process is very short and some monitoring programs are difficult to be conducted.Results showed that the data from FEM proved to be effective in comparison with measured data and the excavation is safe during the shield uplifting.The research results provide references for similar projects.关键词
