摘　　要：首先提出土的综合能量的划分、土的结构熵、土的结构性定量化参数、熵能转化参数的概念,使得复杂多变的土的微观结构要素能用能量状态–结构熵进行量化,打破传统土力学中以均质体理论研究非均质土的框架。描述土的宏观力学效应、微观能量状态两者的构架及其之间的联系,着重探讨宏微观能量状态的相互转化,并通过浸水膨胀性土与非膨胀性土中结构熵的力学效应的表现,说明结构熵理论可以解释微观结构所表现出的宏观力学效应,为土的结构性定量化研究提供一条新的途径。Firstly the division of synthetic energy, the structural entropy of soil, the quantitative structure parameters of soil and the concept of exchange between entropy and energy are proposed. The framework of traditional soil mechanics in which homogeneous theories are applied to solve problems of non-homogeneous soil is changed, and the conception of structural entropy is discussed, which leads to a ration of many complex elements by the unified state of entropy. A quantitative parameter for soil structure characteristics also is provided, which is named entropy and energy exchanging parameter. The principle of macro and micro energy state exchanging will be especially emphasized and investigated.
