Abstract：
The parameters of rock strata are key factors affecting the analysis of tunnel safety, and the determination of parameters is usually based on in situ data monitoring and numerical simulation. Using site-monitoring data obtained by the multi-point displacement meters, as well as numerical calculations achieved by finite element model using the error sum of squares as its objective function, an orthogonal back analysis was performed. The calculation results show that this orthogonal back analysis is feasible and can be used as a reference for similar projects.
