This paper discusses the preservation methods of groundwater flow as countermeasures of solving various problems caused by the groundwater intercept when the underground structures such as the tunnel are constructed under the groundwater level.Firstly,the influences on the groundwater and the environment caused by underground construction are outlined.Secondly,case studies of underground construction concerning groundwater,such as open cut method,NATM method,and shield tunneling,and their countermeasures are described in detail. |
