摘要
声波测试技术是通过获得声波在岩体中的传播时间,计算岩体声波速度,从而分析岩体特征的一种检测技术。本文通过单孔与跨孔声波测试技术获取水布垭电站左岸趾板岩体波速特征,从波速~深度曲线中识别出波速突变拐点,最终确定出松动区和原岩的分界区域,其中电站左岸趾板岩体松弛层厚度一般为1m左右,最小0.1m,最大为2.0m,低波速区松弛层厚度相对较大。岩体声学测试技术及应用是研究水电工程岩体的一种十分有效的方法,可对大坝基岩深度方向岩体特征进行分析,对保证水电工程施工质量具有一定的应用价值。
Acoustic testing technology is spread through time of sound wave in rock mass, calculate the acoustic velocity of rock mass, so as to analyze the detection technique for rock mass characteristics. We get the Shuibuya Hydropower Station Left Bank toe board wave velocity of rock mass characteristics by single hole and cross hole sonic testing technology, from velocity ~ depth curve identify velocity mutation inflection point, and ultimately to determine the boundary area of the district and the original rock loosening, which power station left bank toe board relaxed rock mass thickness general is about 1m, minimum 0.1 M, maximum is 2.0m, low velocity relaxation zone layer thickness is relatively large. Hydropower engineering construction quality has a certain application value to ensure the rock mass acoustic testing technology and its application is a very effective method for study of rock mass in hydroelectric project, carries on the analysis to the dam bedrock depth direction of rock mass characteristics.
