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.
