The Apply of Anisotropy Equivalent Flow Model in Research of Tunnel Drainage Influence Radius
Tunnel drainage influence range is a difficult hydrological problem. It relates directly to tunnel groundwater environment influence degree in construction and operation stages. Based on Shibanshan tunnel in Shijiazhuang-Taiyuan passenger line, this paper analyses influencing factor of tunnel drainage influence radius and flow transient process adopting heterogeneity and anisotropy equivalent flow models. This paper studies the tunnel drainage influence radius and construction progress , hydrology factors, geological factors and rainfall infiltration factors relations. Research results show that the influence factors are rock permeability, rainfall infiltration recharge and aquifer thickness on tunnel top, less influence factors are structure surface direction, anisotropy characteristic coefficient and primary support of the closed time. The conclusions will provide technical supports for evaluating the tunnel construction of groundwater environmental impact.
