摘要：

In order to support cracked tunnel which is under the condition of high stress in Yaoqiao coal mine, we analyze the relationship between ground stress and tunnel deformation based on results of ground stress obtained in situ and put forward the grouting and bolting reinforce technology and the support structure of grouting and bolting with concrete layer. In addition, we define the concerned support parameters according to the ground stress data obtained in situ and numerical simulation results. The result from project indicates that the support problem of the cracked tunnel in complicated high stress area can be effectively solved by such support technology centered by grouting and bolting. The deformation of surrounding rocks can be effectively controlled by using the new support scheme, providing an efficient path for the similar projects.
