According to the water supply project of the central cities of Jilin province ,the mechanical parameters of rock mass at different pressures were obtained through in -situ test using the radial hydraulic pressure pillow method .And then ,the rock resistance coefficient was calculated according to the different rock units resistance coefficient formula . Through comparison ,the resonable elastic resistance coefficient of surrounding rocks was determined .Furthermore ,the lining structure was optimized to meet the security requirements of the surrounding rocks by selecting the appropriate elas-tic resistance coefficient of surrounding rocks based on the analysis and arrangement of the existing indoor and outdoor rock mechanics test data ,the calculation results of empirical formula and the reference value of relevant specifications .
