Study on Grouting Simulation Experiment and Its Application

In this paper, a new technique and method of grouting simulation experiment is introduced. By the grouting simulation test in laboratory, the influences of the feature of grouted meduim structure, water cement ratio and grouting pressure upon grouting amount, grout diffusion radius and injected meduim strength are analysed. The results of the simulation experiment applied in the design of the tunnel grouting engineering are enumerated.
