摘要
通过采用不同水灰比对隧洞不同围岩类型进行灌浆试验,验证和优化设计灌浆参数及灌浆效果,寻求合理的施工程序、工艺及方法,确定各类围岩灌浆材料配合比。
The design grouting parameters and grouting effect were verified and optimized by grouting tests with different water cement ratios for different types of surrounding rocks of the tunnel. The results could be used to search reasonable construction process,technology and methods,and to determine the proportion of grouting material for different types of surrounding rocks.
