Three-dimensional parametric numerical modeling analysis method and system for structure-soil-structure system

Abstract

The invention discloses a three-dimensional parameterization numerical modeling analysis method and system of a structure-soil-structure system. A structure-soil-structure model is simplified into a surface structure, a subsurface structure and a soil mass; the geometric dimensions of the model are converted into parameter variables through parameterization induction; parameterization induction isperformed on the surface structure position, and the surface structure space position is converted into parameter variables; parameterization induction is performed on the subsurface structure position, and the subsurface structure space position is converted into parameter variables; the height and the number of floors of the surface structure are set to be converted into parameter variables; anABAQUS limited element analysis model of the structure-soil-structure model is established through python language; the program is nested in ABAQUS, and visual modeling operation is realized throughGUI development. Mass modeling and quick modeling can be realized through GUI operation, and the labor resource and the time cost consumed during massive modeling can be saved.

Description

technical field [0001] The invention belongs to the field of computer-aided design of surface structure-soil-underground structure, surface structure-soil and underground structure-soil interaction system, and more specifically relates to a structure-soil-structure finite element automatic numerical modeling analysis method and system. Background technique [0002] In recent years, with the acceleration of the urbanization process, more and more urban underground space resources have been utilized, and with the increase in the number of surface structures and underground structures with similar distances, the interaction system composed of surface structures, soil and underground structures are also increasingly complex, so interaction effects should not be ignored. In order to study the seismic response of the structure-soil-structure interaction system, domestic and foreign scholars have carried out extensive research on the interaction system, including indoor and outdoo...
