Aiming at the deficiencies of traditional linear optimization methods in back analyzing, an improved finite element method of rock stress field back analysis coupling with genetic algorithm is put forward, in which the finite element analysis is embedded in genetic algorithm as a single module and rock stress field is gotten by nonlinear solution. Then an assumed geological cross-section is taken for an example to verify its validity. The result demonstrates that the back analyzed stresses of all the measuring points are in good agreement with the measured ones and the relative error is very small, which verifies the feasibility and effectiveness of the proposed method.
