一、概述岩体声波探测技术是为解决工程施工和设计发展起来的,七十年代初,我国声测技术用于地下工程,到目前为止已有四、五百个单位应用了这种技术。岩体声波探测主要用来探测地下硐室围岩松动范围;对工程围岩进行分类及稳定性评价;测定岩体物理力学参数,检测一些工程的施工质量等等。过去岩体物理力学参数及有关地质特征的测试方法,主要是建立在静力学基础之上,这种方法虽然直观、明确,但耗费大量人力、物力和财力,测试周期长,难度也比较大。采用声测技术加快了探测速度,测试受外界条件干扰小,
I. Overview Rock sound wave detection technology is developed to solve the construction and design of the project. At the beginning of the 1970s, China’s sound measurement technology was used in underground engineering. So far, four or five hundred units have applied this technology. Rock sound wave detection is mainly used to detect the looseness of surrounding rock in the underground chamber; classification and stability evaluation of the surrounding rock of the project; determination of physical and mechanical parameters of the rock, detection of construction quality of some projects, and so on. In the past, the test methods for rock physical and mechanical parameters and related geological features were mainly based on statics. Although this method was intuitive and clear, it consumed a lot of manpower, material resources, and financial resources. The test cycle was long and the difficulty was relatively large. Acoustic measurement technology is used to speed up the detection, and the test is less affected by external conditions.
