A series of dynamic triaxial tests of soil samples from intertidal zone were performed under strain-controlled and stress-controlled conditions respectively.The relationships among stress,strain and pore pressure of soil samples under cyclic lifting loads were obtained,and the dynamic properties and liquefaction potential of the foundation soil were analyzed.Finally,some suggestions about construction methods in site were proposed.
