In consideration of most elastoplastic damage model with many parameters and which is not easy to determine, the elastoplastic damage constitutive solving program was compiled by C++ language, and which was integrated into the intelligent parameters back analysis program based on difference evolution algorithm. The accuracy of the constitutive model and the feasibility of the back analysis program were verified by a numerical example. Based on this, the program was applied in damage parameters inversion of hole-pile method in Dalian metro station construction, the damage parameters from inversion of monitoring displacement of the first construction process was used to finite element simulation of the subsequent construction process. Results show that the method and program have good reliability to solve practical engineering problems.
