Analysis on Influence of Tunnel Construction Factors to Groundwater Resources
Considering the fact that the Shibanshan Tunnel of the Shijiazhuang-Taiyuan Passenger Dedicated Line was located in the arid mountain area where underground water resources were lacking, the ecological environment was fragile and tunnel construction had some impact on local domestic and production water supply, study on recovery of the underground water level was made. The influence of construction measures including grouting reinforcement, radial grouting reinforcement and shotcreting and support closing time on recovery of the underground water level was analyzed to provide technical basis for reasonable choice of design and construction schemes. The results show as follows: Recovery of the underground water level is related to engineering factors in the tunnel affected area; different support closing modes cause obviously differentiated effect on recovery of the underground water level whereas little effect is created when referring to the support closing time.
