用损伤力学处理方法着重研究爆破运区岩体的松裂机制，建立其损伤发展方程与本构模型。在二维限差分计算程序（Ｓｈａｌｅ）中嵌入伤模型后，实现了岩体爆破松裂区数值模拟。对三峡工程左岸坝基岩体小药量爆破试验和清江隔河岩工程的开挖爆破进行了模拟计算，其结果与相应的实测数据吻合，模拟相对误差小于１３．３％ Damage mechanics method is used to study the mechanism of loose crack of rock mass in blasting area and to establish its damage evolution equation and constitutive model. After the injury model was embedded in the two-dimensional finite difference program (Shale), the numerical simulation of rock burst zone was achieved. The small-volume blasting test of the left bank of the Three Gorges Project and the excavation and blasting of the Geheyan project in the Qingjiang River are simulated. The results are in good agreement with the corresponding measured data. The relative error of the simulation is less than 13.3%
