Abstract Using the Qindong railway tunnel in the loess area as an example and based on the "load-structure" model, the Monte Carlo finite element analysis and the statistic knowledge, as well as mathematical statistical characteristics of parameters related to surrounding rocks, this paper studies and analyzes the reliability of tunnel lining structures by carrying out structural calculations. A calculation model for reliability design of the tunnel lining structure is established and the statistic characteristics and distribution patterns of the axial forces of a large-section loess tunnel structure are obtained. Additionally, the calculation means available for the reliability design of tunnel lining structures are proposed, providing a guide for the application of structural reliability theory to the reliability design of tunnel lining structures.
