摘要
通过实验室节理岩体模拟模型的电测实验，分析了节理岩体内爆炸应变波的传播规律及破裂形式，并与数值计算的模拟结果相比较，研究节理岩体爆破能量的耗损，为提高节理岩体的爆破效果提供理论依据。
In the paper, the propagation of explosion strain wave and the cracking pattern and energy wastage in the jointed rock mass are analyzed on the base of experiments on simulating model in the laboratory. The experimental results are compared with that of the numerical calculation to provide theoretical basis for improving the crack affects on the jointed rock mass.
