In the dynamic design of tunnel constructed with the New Australian Tunnelling Method,it is important to calculate the reliability of the lining structure by in-situ measurement data of displacements. Following the investigation of variability of random variables including lining displacement,thickness of shotcrete and properties of shotcrete material,the performance functions for section failure are put forward. Two case studies are conducted by using Monte-Carlo simulation to check the rationality and correctness of the proposed method.
