Abstract: Large-scale model tests on vertical deformation of cement-soil pile composite foundation under cyclic loading are performed through a new load-applying system designed by ourselves. It is shown that the critical cyclic stress ratio of cement-soil pile composite foundation is bigger than that of saturated soft foundation and is not affected by cement mixing ratio basically. In addition, cyclic stress ratio and number of cyclics have remarkable effects on vertical deformation of cement-soil pile composite foundation.

Key words: cyclic loading, model test, composite foundation, vertical deformation
