潮间带土在吊装荷载下的动力性质

Dynamic Properties of Soil in Intertidal Zone under Cyclic Lifting Loads

摘要:

对取自如东潮间带的原状土样进行了一系列模拟施工吊装动载的应变控制和载荷控制动三轴试验，得到了土样在动载作用下的应力、应变和孔压随时间的变化关系，并对此种潮间带地基土的动力特性和液化可能性进行了分析，最后针对现场施工方法提出了一些建议。

Abstract:

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.
