摘要: 指出了土骨架的定义、成分即所占据的空间;认为土力学就是研究土骨架的力学性质及其影响因素的学科。用大量的例子,形象地说明土骨架的溃散所造成的严重后果。从土的颗粒出发解释了土中水的渗透力的机理,推导了渗透力的计算公式。特别指出,通常所谓的“渗透力就是渗透水流对于土骨架的拖曳力”的说法是不全面的。

Abstract: Some concepts are pointed out, including the definition of the soil skeleton, its composition and the space occupied by the soil skeleton. It is indicated that soil mechanics is a subject to study the mechanical properties of the soil skeleton and its influencing factors. A large number of examples with some serious consequences induced by collapse of the soil skeleton are illustrated. Based on the analysis of forces on particles, the mechanism of seepage force in the soil skeleton is explained, and the formula for calculating the seepage force is derived. In particular, that generally the so-called “seepage force is the drag force of the soil skeleton by flow of water” is not comprehensive.
