1前言2000年,双洎河流域范围内普降大到暴雨,降雨强度为近20年所罕见。双洎河河水猛涨,80多公里堤防险象环生,部分堤段决口。造成这种情况,固然因为洪水峰高量大,持续时间长,水位高,但与堤防本身存在基础渗漏、管涌等隐患亦有直接关系。目前,防止渗漏、管涌等事故,虽然早已在土坝设计中找到了有关的技术措施,但由于我国堤防线量大,经济上不允许照搬土坝工程的解决方法。垂直铺塑是解决堤基渗漏、管涌等
1 Foreword In 2000, the Shuangbahe River Basin ranged from heavy rain to heavy rainfall, which was rare for nearly 20 years. Shuangbahe River soared, more than 80 kilometers of embankment risk like a relic, part of the embankment burst. This situation is caused by the flood peak height, long duration and high water level, but it is also directly related to the embankment’s own leakage and piping. At present, to prevent leakage, piping and other accidents, although the relevant technical measures have been found in the design of earth dam, due to the large amount of embankments in our country, it is not allowed to follow the solution of earth dam project economically. Vertical shop is to solve leaking embankment, piping and so on
