Abstract: The initial stress field is very important in the finite element analysis of geotechnical engineering structure. In the engineering practice, the rock masses are nonlinear. In this paper, a methodology of initial stress back analysis combining the genetic algorithm and finite element theory is proposed. An example is studied, the results show that the proposed method is reliable and can be applied to the engineering practices.

Key words: genetic algorithm, finite element method, initial stress field, back analysis
