岩土破损力学——结构类型与荷载分担

BREAKAGE MECHANICS OF GEOMATERIAL——STRUCTURE TYPES AND LOAD SHARING

岩土破损力学是不同于岩土断裂力学和岩土损伤力学的新理论。介绍了岩土破损力学中分宏观、细观和微观3个层次的研究方法,把结构性岩土材料划分为碎裂结构、散块结构、包络结构和浮悬结构4种类型,并讨论了分别确定结构体和结构面分担荷载的基本原则。

Breakage mechanics is a new theory different from fracture mechanics and damage mechanics. The methodology of examination for geomaterial in three levels, macro-level, meso-level and micro-level, was introduced, and the geomaterials were divided into four structural types, fragmentation structure, scatter mass structure, envelope structure and suspension structure. The principles to determine the load sharing ratio between structure bodies and structure surfaces for each structural type were discussed. At last, some meaningful conclusions were obtained for the development of breakage mechanics of geomaterial.
