本文概述了作者多年来将弹性波法应用于岩土爆破工程的工作实践。主要介绍试验方法和根据围岩不同的声学特性,选用的不同计算方法,计算围岩的动弹性常数和实例以及围岩加固处理效果的检测办法。给出了围岩的波阻抗分类和应力波参量衰减指数与岩体波阻抗的依赖关系;给出了岩体和坑道破坏分区的定量判据—爆前爆后围岩纵波波速变化白分比。实践证明:弹性波法对岩土爆破工程的爆破效应和破坏机理的研究是一种很重要的、快速、简便、准确的手段,直接影响到岩土爆破的安全和经济效益,有广阔的应用前景！
This article outlines the author’s years of practice of using the elastic wave method in rock and soil blasting. This paper mainly introduces the test methods and the different calculation methods based on the different acoustic characteristics of the surrounding rock, and calculates the dynamic elastic constants and examples of the surrounding rock as well as the testing methods for the reinforcement effect of the surrounding rock. The classification of wave impedance of surrounding rock and the dependence of wave attenuation parameter on the impedance of rock mass are given. The quantitative criteria of rock mass and tunnel damage zoning are given. . Practice has proved that the study on the blasting effect and failure mechanism of the elastic wave method for rock and soil blasting engineering is a very important, quick, simple and accurate method, which has a direct impact on the safety and economic benefits of rock blasting and has broad application prospect!
