Abstract
Genetic algorithm-finite element method (GA-FEM) is applied to the study of tectonic stress field of part of East Asia area. From the observed stress distribution, 2-D elastic plane stress inversion is made to deduce the boundary forces and investigate controlling factors. It is suggested that the continent-continent collision is the dominant factor controlling the Chinese tectonic stress field. The ocean-continent convergence along the subduction zone is an important factor. There exists tensile boundary force along the marginal sea.
