| 摘 要： | 天然岩土材料与其它材料的根本不同点在于它的结构性,而形成结构性的根本原因在于胶结的不均匀性.胶结强的部位形成结构体,胶结弱的部位形成结构面.岩土材料是由结构体和破损带组成的二元介质.本文分析了岩土材料的系统特性,对岩土破损力学进行了介绍,从非线性科学的角度阐述了岩土破损力学的系统论基础.

| Abstract: | Natural geological materials are strongly heterogeneous. The heterogeneity is mainly attributed to the irregular spatial distribution of bonding force between particles. A geological material can be regarded as a structural medium, consisting of bonded lumps or blocks and weakened bands or surfaces with quite different bondings in the different parts of medium. In this paper the system characteristics of geological materials are analyzed . A new theory called breakage mechanics is introduced for geological materials. The theory regards the geological materials as a double-medium body composed of structural lumps and structural bands. The system approach of breakage mechanics is expounded. |
