摘      要：A method of analyzing the stability of twin shallow tunnels was presented using both limit analysis with nonlinear failure criterion and reliability *** the condition of nonlinear failure criterion,the critical clear distancesof twin shallow tunnels were obtained by analyzing the change of surrounding pressure.A reliability model was established based on limit state equation,and the failure probability was solved by virtue of Monte Carlo *** factor and corresponding clear distance of different safety levels were obtained by introducing a target reliability *** scope of clear distance for different safety levels is described,which can be used as a supplement and improvement to the design codes of tunnels.

主 题 词：twin shallow tunnels limit analysis nonlinear failure criterion reliability theory clear distance
