【Abstract】 In this paper, we study several key problems concerning the reliability analysis for railway tunnel lining structure, such as the computing models, basic variables and their statistical characteristics, limit statè equations and reliability index. The feasibility of the conception in composing this paper and the reasonableness of the computing results are shown by examples. The method described in this paper may be looked on as a feasible way of modifying the design specifications of railway tunnels according to the reliability theory.更多还原
