Advanced support is the key measure for tunnel passing through the weak broken surrounding rock. As a common advanced support method, advanced small conduit grouting technology can improve the physical and mechanical properties of rock mass, enhance surrounding rock parameters, and effectively suppress the deformation of surrounding rock. Based on a diversion tunnel project in the west of China, this paper comprehensively evaluates the sensitivity of the physical parameters of grouting reinforcement based on the multi-factor sensitivity analysis method, in order to provide reference for the optimization of advanced grouting reinforcement scheme.
