Simulation Research Of Soil Excavation And Inclination Correction Considering The Interaction Between Soil And Structure

In recent years, the theoretical research on the rectification technique has become a hot issue in the field of structural and geotechnical engineering. Most of theoretical researching of correcting building technique skimpily focalized point on deformation of soil released stress, or only considering the interaction between foundation and soil deformation, rarely considering the mutual influence between the upper structure and foundation deformation. The research object is the complete rectification system composed of superstructure, foundation and soil, the three are mutually interaction. The rectification technique should be based on the depth of the soil to dig soil. The plastic zone around the hole is closely related to the stiffness of the upper structure and foundation. In the rectification process, without considering the interaction between superstructure, foundation and foundation of the plastic zone around the hole soil, there is a big difference between the actual and the theory. Therefore, it is necessary to establish the finite element model of the upper structure, foundation and foundation, which is in accordance with the actual process of digging the soil.In this paper with a 11 storey residential building in Jiangsu rectifying slope reinforcement engineering as background, with reference to the structure design of the upper structure, foundation and soil interaction theory, according to the data of field engineering,using AB AQUS finite element analysis software, the finite element model of the building with the combined effects of superstructure, foundation and ground is established, three dimensional finite element model is analyzed in the process of soil excavation and rectification in residential buildings. The following four aspects are analyzed:Considering interaction and without considering the interaction of building sedimentation comparative is analyzed. Considering the interaction and without considering the interaction of soil around the hole Mises stress comparison is analyzed. Considering the interaction and without considering the interaction of the soil around the hole displacement is analyzed.Comparison of upper structure stress before and after the rectification of buildings is analyzed. The differences of stress and displacement of soil around the hole are obtained and compared with the measured data, the feasibility and rationality of the buildings rectification technique of considering the combined action are verified.
