Abstract
In order to understand the compaction effect of dam foundation rock mass during concrete grouting process, the in-fluential factors on compaction effect, the timeliness of compaction and features of drilling panoramic picture were studied by u-sing testing results of single-hole sound-wave and drilling panoramic picture of long-term observation hole after consolidation grouting. The results show that the dam foundation rock mass has an obvious compaction effect with the increase of the grouting thickness, the rock mass velocity increases gradually and the joint opening decreases or even disappears; the concrete cover thickness and initial rock wave velocity are key influential factors on rock wave velocity increment.关键词
