摘要: 考察了当前对土结构性及其定量化指标研究的现状和方法，提出了一个既能反映结构性关于颗粒排列（即几何特征影响），又能反映结构性关于颗粒联结（即力学特征影响），并具有简便、明晰特点的结构性定量指标———综合结构势。然后通过试验检验了这个定量化参数在表征结构性对土性影响方面的良好功能和合理性。

Abstract: In this paper, the approach to study the soil structure quantitatively and the situation of the study are analyzed. A new structure parameter comprehensive structure potential (CSP) which can demonstrate both the characteristics of the soil particle arrangement (i.e. the geometric feature of soil structure) and the soil particle linkage (i.e. the mechanic feature of soil structure) is proposed. This parameter is easy to be obtained and distinct in its mechanism. It has been proved through a series of experiments that this parameter is not only efficient and reasonable to consider the influence of soil structure on its property, but also sensitive to the factors affecting the soil structure.
