Research on the Geostatic Stress Field Procedure under Complex Conditions

Geostatic stress field procedure is the first and most important step for numerical simulation of geotechnical engineering, which greatly influences results. Traditional methods often fail when model complex. In this paper, based on finite element method (FEM) software ABAQUS, failure reasons four commonly used geostatic are studied. According to analysis results, a new set methods, can provide reasonable displacement results under complex conditions, proposed. The proposed follow principle that different materials should be obtained separately avoid distortion. Then, accuracy applicability verified through comparison study specific application. This provides theoretical basis condition serve as reference relevant studies.
