Then, on the basis of the expression for notch strength of brittle material and the fundamental principle of probability theory, correlations between the statistical characteristic parameters o.
Based on the theory of quasi-static explosion gas dilation and the principle of rock fracture mechanics, Brittle rock fracture model is developed for notch blast with non-coupled charge explosion.
基于准静态爆生气体膨胀和岩石断裂力学理论，建立了不耦合装药刻槽爆破时的脆性断裂爆破模型。
