As one part of the research program of study on reliability of stability of high rock slope and optimization of support , the thesis does further study on blasting and achieves some results as follows : ( 1 ) the interaction of shock wave and explosive gas due to blasting is the important cause to the destroy of the rock . the rock in the line of every hole is easiest to be destroyed while single - row blasting . dynamic loads of blasting can be simplified to triangular loads 本文作為“巖質高邊坡穩定可靠性與支護結構優化研究”研究課題的一部分,對邊坡工程中的爆破施工進行了深入的研究,主要取得了以下成果: ( 1 )沖擊波和爆生氣體的共同作用是引起巖石破壞的重要原因;單排爆破中炮孔連心線上最容易破壞;爆破動力荷載可以簡化成三角形荷載。
