Simulation and Parameter Identification Method of Tunnel Based on Differential Evolution
Research of tunnel surrounding rock deformation and stability possesses significant role of theory and tunnel construction. As the underground geological body has complex and uncertainty characters, we exploit a tunnel simulation program EEOS based on difference evolution algorithm and finite element method in this paper, which can simulate the displacement and stress distribution of tunnel excavation and identify actual surrounding rock mechanics parameters. Based on the discussion of algorithm and calculation process, we carried out research and demonstration of a calculation example, the outcome of tunnel simulation and analytical results comparatively accord. Identify the elastic modulus and Poisson ration of the rock using difference evolution algorithm, we got super recognition accuracy and favorable convergence performance. The computer simulation and parameters identification program developed has active meaning for tunnel engineering.
