帷幕灌浆,在灌浆前后一般都要压水,以了解岩石的透水性;有的还要钻孔了解灌浆的质量。这些方法工艺复杂,工期长,费用大。为了改进这一工艺,我们在鲁布格电站帷幕灌浆试验中,对采用声波测试法来检测灌浆质量进行了初步探索。所谓声波测试法,即是利用弹性波的传播特征,了解岩体的物理状态,将岩石的完整性、裂隙等变为声学参数的信息反
Curtain grouting, before and after grouting generally have to pressure water in order to understand the water permeability of rock; some also drill to understand the quality of grouting. These methods complex process, long duration, costly. In order to improve this process, we carried out a tentative exploration on the quality of grouting by using the acoustic testing method in the curtain grouting test at the Ruibu Hydropower Station. The so-called sonic test method, that is, the use of elastic wave propagation characteristics to understand the physical state of rock mass, the rock integrity, cracks and other information into acoustic parameters of the anti-
