| Abstract: | The shield driving method,as one of the main construction methods of metro tunneling,has been used widely in China.The stratum movement and ground settlement induced by such construction are main issues receiving much concern during shield tunnel design and construction.Based on the shield tunneling of Shenzhen Subway Line 5 traversing Guangshen highway flyover,a 3D Fast Lagrangian Analysis of Continua is used to simulate the shield tunnel construction and analyze the ground settlement and bridge pile defor... |
