摘要
以梁山隧道DK99+155处软弱带为例,详细介绍了超前帷幕注浆加固软弱带的施工工艺,并对注浆效果进行了评价,指出通过采用超前帷幕注浆加固,地下水被有效控制,在开挖轮廓线5 m以外,为同类工程提供了施工指导。
Taking Liangshan tunnel DK99 ＋ 155 weak section as an example, this article specifically introduces construction technology of advanced curtain grouting for reinforcing weak section, and evaluates the grouting effect, and then points out that： underground water can be effectively controlled over 5 m of excavation contour by adopting advanced curtain grouting reinforcement technology. Thus, it has provided construction reference for similar engineering.
