| 摘 要： | 传统的波阻抗匹配观点正在受到来自工程爆破实践和岩石炸药波阻抗匹配的试验和分析结果的冲击。作者分析了传统波阻抗匹配观点的不全面之处,在此基础上,用较为全面地反映药卷爆轰与孔壁作用过程的模型,以传递到岩石介质中的爆炸能量最大为目标,通过理论分析和数值计算,给出了合理匹配时岩石与炸药参数间的关系,经验证,可以用来作为一种选择炸药的依据。

| Abstract: | The traditional matching view of wave impedance is not in good agreementwith ractical experience in engineering blasting and some experimental resultsabout the matching of mpedance between rock and explosive.The authors ana-lyze the shortcomings of the traditionalm rching view,and obtain the relationsbetween parameters of rock and those of explosive in the ondition of the rea-sonal matching between rock and explosive according to a model which is oreaccurate to simulate the action of explosive detonating wave to rock wall thanthe raditional model.The results are in good agreement with practical experie-nce in engineering lasting and some experimental results.This new matchingrelation can be used as a proper basis or selecting explosive in rock blasting. |
