| 英文摘要 | Underground engineering exists in complex geological environment, the uncertainty of rock mechanics parameter becomes a key problem restricting safety calculating based on numerical simulation, Combining a global intelligent optimization-difference evolutionary algorithm, three dimensional numerical simulations and orthogonal design principle, the paper proposes an underground safety feedback analyzing method based on monitoring data. Firstly, according to the orthogonal design principle, three numerical experiments are adopted. Then the high sensibility parameters are selected to construct the response surface regression function that can compute displacements of surrounding rock instead of large scale numerical simulation. Adopting the regress function in the objective function of DE optimization algorithm, the mechanics parameters could be identified rapidly by the greedy selection process of DE. Using the method, the safety of the tunnel of Tuyang high speed way is simulated and analyzed. The result states that the proposed method has good convergence property and computing accuracy. The acquired parameters have guiding action to the tunnel construction and long term stability evaluation. The method can effectively utilize the large business software, has both theory and application value. |
