摘要:
选用合适的应力强度因子,使之符合切缝药包控制爆破初始裂缝形成和裂缝扩展的过程。从分析切缝药包控制爆破裂缝形成机理入手,运用弹性及弹塑性理论对切缝药包爆破形成的裂缝及扩展进行力学分析,提出了适合于弹塑性条件下初始裂缝形成的应力强度因子。根据弹塑性理论得出的使岩石产生裂缝的应力强度因子经现场应用较为符合实际情况。
Abstract:
The suitable stress intensity factor was selected to fit in with the initiation of cracks and subsequent propagation in rocks during controlled blasting in cutting seam cartridge. Starting from the mechanism of the cracking process, elastic-and elastic-plastic theories were applied for the mechanical analysis on the initiation and propagation of cracks due to cutting seam cartridge blasting to determine the stress intensity factor under the condition of elasticplastic. Stress intensity factor, which is based on the theory of elastic-plastic and cracking in rocks, is proven to be consistent with the practical -situations.
