Analysis of Water-Rock Interaction and Two-Dimensional Seepage Field of Tunnel

Abstract:

Researches show that groundwater easily leads to tunnel disease. Groundwater seepage field is changed after the tunnel excavated. When crossing the fault fracture zone with groundwater, the tunnel will be cut into independent units with water. Along with the tensile stress on the tunnel invert and upper apex, it's prone to landslides and other damages. This paper analyzes the mechanism of interaction of water and rock, and describes the failure mechanism made by groundwater on the rock by RFPA2D, then analyzes the changes of groundwater seepage field before and after the tunnel excavation by using Rocscience Slide, finally the conventional Inflow prediction methods are contrasted.
