摘要：

Aiming at the complexity and uncertainty of rock and soil body, the paper the paper introducing a new global intelligent optimization arithmetic - Difference Evolution (DE) and combined with stress return mapping nonlinear elastic-plastic Finite Element Method(FEM), realizing rapid elastic plastic parameters identification of surrounding rock. The analytical theory and method are introduced in detail, analyzes the tunnel of Dalian Metro by the proposed method, and gets satisfied results.
