| 摘 要： | 指出岩体爆破破碎的过程是岩体内原有裂隙发育和损伤增长的过程，是宏观损伤和细观损伤综合作用的结果。利用Ｌｅｍａｉｔｒｅ等效应变假设，分析了细观损伤演化与宏观损伤演化的耦合，提出了一种岩体爆破破碎综合损伤计算模型。

| Abstract: | The paper argues that the process of rock fragmentation is the one of increasing damage and inherent fracture in rock,and is the coupling damage result of the micro damage and macro damage.The coupling damage evolution of micro damage and macro damage evolution is analyzed using Lemaitre hypothesis.Besides,the paper presents a damage evolution model for the rock blasting fragmentation. |
