| 摘 要： | 岩体爆破效应的声波探测是通过检测声波在爆破前后的岩体中的声学参数(声波波速、衰减系数、波形、频率、振幅等)的变化,间接地分析岩体内结构状态、力学参量以及爆破震伤程度等的一种测试技术.探测的结果不仅可以测定岩体的物理、力学特性,而且能定量地判断出爆破前后岩体的变化状态,为爆破设计提供依据,并能正确评价爆破效果.文章描述声波探测法基本原理,岩石特性对声波波速的影响,岩体爆炸破坏的判断依据,对今后的声波测试技术深入研究提出了一些建议,并展望了在今后工程中的应用前景.

| Abstract: | Acoustic sounding in explosive rocks is a testing technology to analyze the structure,mechanics parameters of rocks and degrees of exploded rocks.The results not only can determine mechanics characteristic of rocks,but also can verdict changes in rocks.It can supply basic for exploding design and appraise the exploding properly.It is mainly concerned about the basic theories of acoustic sounding and physical properties of rocks' influence on acoustic sounding.Meanwhile, the basis of appraising effects of exploding and some suggestions of it in depth research are presented. Application of acoustic sounding is also predicted in the future. |
