The Construction Technology and Numerical Simulation on Tunnels Throughing Fault Fracture Zone with Rich Water

Abstract:

Fault fracture zone with rich water has some bad geological conditions such as low strength, deformation, strong water permeability, poor water resistance. Landslide has been happened because the water permeability. This paper is based on Yan-jia Tunnel in HuBei-Guzhu Highway. For the bad geological conditions, WSS is taken as the advanced support method to reinforce soil and stop watering. The method has improved the construction condition. To reduce the excavation area in one time and the disturbance to surrounding soil, the construction method of meshshotcreting firstly is adopted. The paper also do the numerical simulation with the numerical calculation tool of the software ABAQUS. The result is basically consistent with the field measurements, which has significance on the subsequent design and construction of underground projects with similar geological conditions
