| BREAKAGE MECHANICS OF GEOMATERIAL——STRUCTURE TYPES AND LOAD SHARING |
|
|
|
|
Abstract Breakage mechanics is a new theory different from fracture mechanics and damage mechanics. In this paper the methodology of examination for geomaterial in three levels，macro-level，meso-level and micro-level，is introduced in detail，and the geomaterials are 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 are discussed. At last，some meaningful conclusions are obtained for the development of breakage mechanics of geomaterial.
