| 摘 要： | 本文对粘性土的塑性和塑性指数的物理意义及其对饱和软粘土力学性状的影响进行了深入研究，归纳了国内外关于这一领域的一些研究成果，结合笔者的试验研究分析了饱和软粘土的塑性指数对若干变形参数影响的定量关系。这些参数包括压缩指数、回弹指数、次固结系数、初始再固结体积压缩系数等。上述关系有较好的相关性，可用于工程计算。

| Abstract: | The physical meanings of plasticity index of cohesive soils and its influencing mechanism on the mechanical properties of saturated soft clays are analyzed. Based on the research findings of predecessors and combining with the experimental data accumulated by the authors, the quantitative relationships between some deformation parameters of saturated soft clays and plasticity index are established. Theses parameters include compression index, expansion index, coefficient of secondary consolidation and initial coefficient of re consolidation volume compressibility, et al. The results can be used in engineering practice. |
