【Abstract】 The construction method and the design of supporting structure of Beijiang Metro between Ciqikou and Chongwenmen are introduced. By using finite element method(FEM)the numerical simulation of building the main strusture of partial underground tunnel is given. So as to know of the stress,displacement in the process of building an underground tunnel,command the key factors that affect the stability of hollows and then adopt relative measures to ensure safety.更多还原
