摘要
利用云南省富源县响水河水库帷幕灌浆试验研究所获得的岩体声波测试成果,提出了以岩体完整性指数评价灌浆效果的概念,并在GB50218-94中Kv值与定性划分岩体完整程度对应关系五级分档[1]的基础上,提出了适合于灌浆质量控制要求的八级分档标准,且灌前灌后的岩体完整程度按八级分档时以提高一级为宜。研究成果可供同类工程借鉴。
Based on observed rock acoustic wave results obtained in the curtain grouting test at Xingshuihe reservoir in Fuyuan County, Yunnan province, a concept of rock integrity index is put forward to assess the grouting effect, and on the basis of the 5-grade rock integrity classification depending the value of K\-v stipulated in GB50218-94, an 8-grade rock integrity classification standard is proposed. This classification standard meets the requirements of grouting quality control. The rock integrity before and after grouting should be raised by one grade for this 8-grade classification standard.
