摘要：
The surface settlement and tunnel lining has a great relationship. To better understand the lining's stress state and influence of surface deformation caused by tunnel lining, base on Finite Element Method, using ABAQUS Finite Element Analysis Software, analyzed the change of surface displacement and the lining of stress and deformation, respectively, with and without lining. Through the comparison of two cases, the surface settlement and horizontal displacement can be effectivly reduced. The influent range caused by excavation is greatly narrowed. Because the role of soil, the compressive stress is beared by lining, and the maximum stress is located at both sides of arch waist. These will be referenced for future design and construction.
