弹性波在基岩检测中的试验研究

Test and Study of Elastic Wave in Base Rock Detection

介绍跨孔波速测试方法和CT探测技术方法原理,并将其应用于对冲孔桩的冲孔前后岩体破坏研究,结合实际冲孔过程进行探测研究,研究结果表明弹性波可以用于探测岩体破坏,探测结果可以定量分析岩体破坏程度,而且结果直观,达到高精度和高分辨率的精细探测要求。

The measuring and testing method for the wave speed of span bore hole and the technical method and principle for CT detecting are introduced. Which are applied to the study of rock damage before and after percussion boring and detection study are given combining with the process of actual percussion boring. The result shows that the elastic wave can be used to detect the rock damage. Because it can analyze rock damage quantitatively and the result is very audio-visual, reach the requirements of high accuracy and resolving power.
