The sixth Chongqing metro line is taked for example, numerical simulation is applied for finite analysis and calculation, the safety of the primary support and the second lining are calculated respectively in different level of surrounding rock, double hole case,different bedrock and overlying abandon ballastless thickness for 45 cases,and then based on the result analysis and calculate the rational buried deepth of the surrounding rock under the different level, And according to the actual measurement of deformation calculation value and deformation value of hole is used for comparison, reference and basis for the similar case is presented.
