海相软土三轴流变试验研究

Experiment Study on the Theology of the Marine Facies Clay

采用应力控制式三轴流变仪对连云港海相软土进行试验,根据分级加载的方法,记录时间和土体的变形量、孔隙压力值,得到土体的应力-应变-时间关系曲线,从软土流变性质上分析解决软土地基工程事故,对海相软土的地基处理、海相软土地区高速公路和房屋建筑的设计施工有着重要的理论意义和工程指导意义。

In this paper,the authors carried out the indoor experiment for the rheology and structure of the marine facies clay with the method of the classify straining by using rheology Instrument of three stalks,recording the time and soil deformation,the pressure of aperture gap and obtained the relation curve of stress-strain-time.The study has important theoretical meaning and engineering meaning for analyzing and solving the engineering problems involving clay foundation from the clay chemistry property and superhighway and house building in the area of the marine facies clay.
