摘要：
Genetic algorithm is an adaptive procedure that finds solutions to the inverse problem by an evolutionary process based on the natural selection. The application of genetic algorithm for solving the non-linear inversion of the initial stress fields is discussed. The inversion algorithm was built to identify the initial stress fields according to the observing data of deformation convergence during the tunnel excavation. The numerical calculations testify that the genetic algorithm for solving the inverse problem is robust, global and generally simpler to apply.
