| Abstract: | This paper studies the deformation of tunnel caused by the excavation of foundation pit around the metro shield tunnel.Combined with the engineering examples,the deformations of foundation pit and tunnel under the different reinforcement conditions are analyzed by using the finite element analysis software PLAXIS,and the auxiliary protection measures of soil reinforcement outside shield tunnel and surcharge inside tunnel are analyzed and demonstrated so as to select the economical and safe construction scheme,which provides a basis for solving the practical engineering problems. |
