The Application of Equivalent Flow Model in Groundwater Resources Loss Estimate of Fractured Rock Tunnel

Abstract:

This With the deepening of sustainable development strategy, groundwater environmental problems caused by tunnel projects are becoming more and more outstanding. This paper estimate the groundwater resources loss of fractured rock tunnel adopting equivalent flow models. In order to increase the model fidelity, the author considers the nonhomogeneous and anisotropic characteristics of fractured rock. Based on Shibanshan tunnel in Shijiazhuang-Taiyuan passenger line, this paper estimated the groundwater resources loss of fractured rock tunnel in construction stage and operation stage, which provides technical support for decreasing loss of groundwater resources.
