| Abstract: | Combined with the project of a loess tunnel, we calculate the deformation of tunnel surrounding rock under different length of pipe roof as well as the stress through 3D finite element simulation. Analysis of different length of pipe roof reinforcement effect in the entrance section of the tunnel was made, it is illustrated that the use of grouting reinforcement in the loess tunnel construction technology can effectively guarantee the stability of surrounding rock. |
