The Total Safety Factor Method for Tunnel Support Structure Design

The Total Safety Factor Method for Tunnel Support Structure Design systematically discusses the entire process of mining tunnel design, including: analysis of surrounding rock self-stability; identification of local support and system support; calculation of rock pressure design value; load structure model and total safety factor calculation method of multi-layer support structure; deformation calculation method of support structure; integrated design method of support strength-deformation-timing; and the dynamic adjustment method based on on-site deformation monitoring.It also presents the inspection and verification tests of total safety factor method and specific engineering application cases.The theoretical system of total safety factor method described in this book has broken through the design bottleneck of tunnel support structures that have long relied on engineering analogy methods.The The Total Safety Factor Method provides the basic theoretical guidance for the quantitative
