摘要
岩土工程问题的有限元分析一般需要考虑初始应力场。实际工程中,岩体往往为非线性。本文采用遗传算法与有限元联合反演法求解非线性岩体初始应力场,通过算例说明文中所提方法是合理的,可在工程应用中推广。
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.
