摘要

以中山港地区软土为主要研究对象，将现场收集、室内实验和原位测试得到的一系列的物理、力学指标进行了统计分析，并将统计结果与南沙和整个珠三角地区的软土进行了对比分析.分析结果表明：虽然该地区软土的含水率、孔隙比、压缩系数的变化范围均要低于其他两处，但其本身的抗剪强度低，力学特性仍较差.通过建立各项指标间的线性和非线性回归方程，研究其相关性程度，得知其孔隙比、含水率、干密度间的相关性最佳.通过分析中山港地区不同区域软土的含水率、孔隙比、压缩系数、黏聚力4项土性指标沿深度的变化规律，揭示了其区域性差异特性.研究结果可供该地区工程建设参考.

Abstract

This paper takes the soft soil in Zhongshan port area as the research object. Many physical and mechanical indexes obtained from the spot

laboratory test and in-situ test have been analyzed. The results

which are compared with the soft soil from Nansha and Pearl River Delta

indicate that the variation of the water content

void ratio

compressibility in here are lower than these in other places. But its mechanical characteristics are still poor because of its low bearing capacity. In order to understand the relationship between the indexes

the linear and nonlinear regression equations are established. This research shows that the correlations of void ratio

moisture content and dry density in this area are the best. By analyzing the water content

void ratio

compression coefficient and cohesive force in different places in Zhongshan port area to describe the longitudinal variation curve

the curve shows that the soil indicators of the longitudinal change rule have regional differences. The results can be used for reference in the engineering construction in this area.
