摘要
首先利用超声波探测法对节理裂隙岩体进行了声波测试,对不同的节理裂隙岩体进行了质量评估。然后通过对节理裂隙岩体进行爆破漏斗试验,分析了节理裂隙对岩体中爆炸应力波传播、岩石破碎及爆破漏斗形成的影响,得出了一些有益结论,对节理裂隙岩体理论研究和指导工程实践具有一定的参考价值。
Utilizing the technique of uhrasonic detection on jointed and fractured rock masscs, the author firstly measures the elastic wave velocity, then appraises the quality of different masses. Secondly, experiments on explosive funnel are conducted, and the paper discusses the influences of the joints on propagation of shock wave, the rock breaking and formation of explosive furmel. Some beneficial conclusions are drawn which are available for references to practical projects and theoretical research of jointed and fractured rock masses.
