Comparison Study Of Analysis Method Of Seismic Pile-Soil-Structure Interaction

The seismic pile-soil-structure interaction (SPSSI) is one of the focus topics of geotechnical engineering and earthquake engineering, and is also the main reseach topic for the bridge seismic design. The seismic pile-soil-structure interaction for bridge structures is lack of systematic study in China currently, especially for the comparison study of the analysis and test results.In this paper, based on the XiaZhang Bridge pile - soil - structure interaction shaking table test results, comparison study of the calculation results of several commonly used simplified analysis model and the test results has been doneThe main contents and achievements of this thesis are described as follows:1. Based on a lot of literatures at home and abroad, the analytical methods and tests about the issue of pile-soil-structure interaction was summarized;2. Lots of test data processing work was done for the pile - soil - structure interaction shaking table test of the XiaZhang bridge , and by use of finite element software ANSYS several commonly used pile - soil - structure interaction simplified calculation model have been set up.3. Comparison study of the calculation results of different simplified analysis model and the test results has been done, and the calculation accuracy of the commonly used simplified analysis models was checked by the test results .4. Some suggestions for the project were put forward.
