爆生气体作用下岩石裂纹的扩展机理
Mechanism of Rock Crack Growth under Detonation Gas Loading
摘要
Abstract
Under the detonation gas loading, the cracks near the hole extend under the gas-driven and the father cracks grow under the gas pressure and the in site stress. Based on rock meso-damage and fracture mechanism, it is presented that the crack growing is the removal process of damaged zone due to the gradual damage from the crack tip to the around rock. The damage and fracture criterions and the damage localization models at the crack tip are individually established, which can better realize the true process of the crack growth under the detonation gas loading.关键词
