摘要
介绍了北盘江光照水电站坝基固结灌浆效果物探声波检测的方法、原理及现场工作布置,针对不同测区的岩体,对灌浆前后波速提高幅度及提高率进行了分析计算,利用达标法和对比法进行比较,最后采用达标法综合评价光照水电站坝基固结灌浆效果。
This paper introduces the geophysical prospecting sonic testing method and principle of the consolidation grouting effect of the dam foundation in the Beipanjiang Guangzhao hydropower station. According to rock from different surveying areas,it makes analysis on the increase and efficiency of the wave speed before and after grouting. Comparing the two methods of standard evaluation and contrasting evaluation,it finally adopts the standard method to evaluate consolidation grouting efficiency of the dam foundation in the Guangzhao hydropower station.
