| Geotechnical centrifuge modeling is the test method that studying the prototype character by simulating the same stress with the prototype in model. Today it had arose abroad attention in the world, many country study the complicated geotechnical engineering by the centrifuge test. With the development of the geotechnical engineering in our country, problem appear ceaselessly, which make the methods of laboratory study and numerical analysis are not sufficient to solve the problems, the centrifuge test turn into the new and efficiency experimental way. So study the application of centrifuge modeling test in geotechnical engineering have the important meaning on theory and practice value. This paper aimed at the mainly problem in geotechnical domain, and the following centrifuge model tests were carried out: 1. In the centrifuge model test of the construction of Chahanwusu CFRD on deep overlying, the conclusion was drawn, namely it is feasible that the CFRD be construction on deep overlying, with the toe slab directly construct on deep overlying, the vertical seepage control by concrete cut-off wall, and the connection of cut-off wall and toe slab by two connect slabs. 2. In the centrifuge model test of wedge failure of rock slope, based on the simulation of the wedge failure of rock slope, evaluated the applicability of Hook method and energy method in analysis the wedge failure. 3. In the centrifuge model test of Yangshan harbor, based on the centrifuge modeling test, the analysis formula which can calculate displacement from the strain of pile was drawn, and the problem that the displacement of underground structure can't measure expediently was settled. 4. In the centrifuge model test of Huanghua harbor project, the prototype construct process was simulated by pitching stone at high speed in centrifuge depend on the equipment developed by ourselves, after that the effect of the pitch was observation by apparatus, and some proposes were put forward for the design advanced.
