Abstract: 
According to the load-structure method, the wall rock with lining can bear the load caused by the surrounding rock, and the rock resistant coefficient (RRC) is a key parameter for evaluating the capacity of this wall rock. Based on the mohr-Coulomb yield criterion, this paper develops a formula for calculating the RRC, which has been applied to the real engineering project, such as Xiamen Xiang’an East Passage underwater tunnel Project. The fact shows that this formula is helpful for designers to determine the RRC value.
