| Abstract: | To choose the optimum construction method of metro tunneling,we conducted research with numerical simulation on strata consolidation subsidence by dewatering,dynamic dewatering,and non-dewatering construction method,taking the integrated effects of fluid-solid coupling and tunneling mechanics into account.We obtained the curved surfaces of ground surface subsidence and strata consolidation subsidence.The results show that the quantity of ground surface subsidence is 31 mm for the non-dewatering method,39 mm... |
