    摘要:

    在西藏高原地区第四系冰碛和湖积松散堆积层防渗加固中,针对高原特殊的气候条件、工程地质与水文地质条件,通过改进高压摆喷设备与工艺,优化设计参数,取得了较好的防渗加固效果。工程实例表明,在高寒冻融地区,采用高压摆喷灌浆防渗加固技术,对砂砾石土坝进行加固处理,技术可靠,经济合理,效果明显,是一种有效的防渗处理方法,值得在高原地区进一步推广使用。

    Abstract:

    In the anti-seepage reinforcement for the quaternary ice conical cap and unconsolidated lacustrine accumulative formation, and according to the special plateau climate, engineering geological and hydro-geological conditions, high-pressure swing spraying grouting equipment & technology were improved and design parameters were optimized with ideal reinforcement effect achieved. It was verified by engineering example that in paramos freeze thawing region, seepage prevention by high-pressure swing spraying grouting was technically reliable and economic reasonable with obvious effect, which was worth popularizing in plateau area.
