【 摘 要 】

Large section soft rock highway tunnel has the construction of large highway engineering. In the process of excavation, large section highway tunnel is prone to large deformation with the poor stability of surrounding rock and complex stress. We determined the deformation of the large section soft rock highway tunnel. Through a comprehensive code comparison, based on the scene early monitoring, the paper guaranteed the quality of the reserved deformation rate of the tunnel, which was optimized and verified in engineering practice based on monitoring and measurement in a certain quality assurance rate. The reserved deformation of rock mass was feasible, fully reflecting the characteristics of information construction methods. It provides reference for identifying similar construction of soft rock highway tunnel with large cross section deformation.
