Inverse analysis for rock mechanics based on a high dimensional model representation

Mechanical parameters of rock mass are essential in engineering for stability analysis, supporting design, and safety construction. The inverse analysis has been commonly used to determine the mechanical mass. In this study, a novel approach was proposed through combing high dimensional model representation (HDMR), Excel solver, numerical model. HDMR employed approximate nonlinear function between response based on Solver adopted search analysis. method verified illustrated performance by two tunnels. were determined displacement surrounding using solver stress computed method. There an excellent agreement with real value or contour that actual results demonstrated practical accurate. It also made it convenient be applied monitored information.
