The Application of Tunnel Monitoring and Measurement in Yanjia Tunnel of Guzhu Expressway
Fault fracture zone with rich water has some bad geological conditions such as low strength, deformation, strong water permeability, poor water resistance. This paper is based on Yan-jia Tunnel in HuBei-Guzhu Highway. WSS is taken as the advanced support method and has improved the construction condition. the construction method of meshshotcreting firstly is adopted. The result of numerical simulation with ABAQUS is basically consistent with the field measurements, which has significance on the subsequent design and construction of underground projects with similar geological conditions.
