摘要
本文通过机械方法产生高压气体，以模拟爆生气体单独作用下的破岩作用。试验表明，爆生气体的破岩过程可用准静态和静态力学来分析，建立在拉伸破坏基础上的静态平衡方程和爆破的实际效果一致，从而证明了爆生气体破岩的拉伸破坏本质。
By mechanical method, high - pressured air is produced to be used in simulatingthe breaking process of rock subjected to the explosion gases. Experimental results showthat this process is quasi - static and the static equilibrium equation based on tensile failure theory has a good agreement with practice. Consequently, the tensile failure natureof rock breaking by explosion gas is revealed.
