土的结构包括土团粒或颗粒的几何排列(即组构)及粒间结合力两个方面。目前还不能对土的结构作定量分析,也不能直接用到土力学计算中去。但是它有助于阐明土的工程性质的作用机理,解释某些特殊土的性状,预测土在外界因素作用下的变化规律,对工程作出最后判断,进而采取工程措施。 最早注意到土的结构性的是太沙基,他在1925年就提出了蜂窝状结构,用以说明在水中沉积的粘土的不稳定的凝聚结构。以后又发展到卡片或书本式结构。这些都是以单个颗粒的
The structure of soil includes two aspects of the geometric arrangement (ie structure) of soil particles or particles and the interparticle binding force. At present, it is not possible to quantitatively analyze the structure of soil, nor can it be used directly in soil mechanics calculations. However, it helps clarify the mechanism of the engineering properties of soil, interpret the characteristics of some special soils, predict the change law of soil under the influence of external factors, make final judgments on the project, and then adopt engineering measures. The earliest observation of the structural nature of the soil was Taishaji, who proposed a honeycomb structure in 1925 to illustrate the unstable cohesive structure of the clay deposited in water. Later, it has developed into a card or book structure. These are all in single particles
