Abstract: The whole construction process of a metro station is simulated by using the covered top-down construction method. The calculated results better reflect the inheritance relationship of the structural response between the construction stage and the servile stage, resulting in more accurate internal force and deformation. Besides, some new methods are also proposed to choose the lateral earth pressure and to modify the brace stiffness of the asymmetric structure. It is more reasonable to make the lateral earth pressure vary with the excavation process. It may provide reference for the design of the similar projects.
