    上海软粘土微观特性及在土体变形与地面沉降中的作用研究

    THE MICROSCOPIC CHARACTERISTICS OF SHANGHAI SOFT CLAY AND ITS EFFECT ON SOIL MASS DEFORMATION AND LAND SUBSIDENCE

    • 摘要: 对上海软粘土的颗粒及集合体成分、孔径分布、微结构、孔隙溶液与阳离子交换性作了分析 ,对固结前后的孔径变化与人工回灌对土体性质可能带来的影响作了探讨 ,从物理化学角度阐述了软粘土微观特性对土体固结变形及地面沉降的影响.

       

      Abstract: A large volume of analysis of grain size, aggregate components, pore size and distribution before and after consolidation, and micro-structure and pore solution composition and exchangeable cations of soft clay in Shanghai was conducted. The possible effect of the pore size variation with consolidation and artificial injection is discussed. And the effect of microscopic characteristics of soft clay on consolidation and deformation of soil mass is depicted from physico-chemical theory. At last, in this paper a new ideas of controll on consolidation and deformation of soft clay is presented.
