饱和软土地基震陷研究

Study on Seismic Sinking of Saturated Soft Soil Foundation

本文通过对渤海湾海底软粘土的动三轴试验研究,探讨了软粘土的动孔压和动变形特性;动孔压与残余应变的关系;建立了计算软粘土震陷的孔压参数模型,并用该模型对'渤海六号'的实测资料进行了验算。本研究成果可用于分析建在软粘土地基上的建筑物的动力稳定性。

This paper researches into the charateristics of dynamic porous pressure and dynamic deform, in study of dynamic triaxil test of sea floor soft clay in Bohai Bay, and the relationship of dynamic porous pressure and remaining strain,and establishes the parameter model to calculated the porous pressure of the soft clay seismic sinking, and checks the site materials of Bohai Jack -up No.6 with this model. This research result can be used to analyse the dynamic stability of the building on the soft clay foundation.
