浅议堤防加固措施

截至１９９８年底的统计，我国江河湖海堤防总长度２５．８万ｋｍ。由于大部分堤防修筑年代久远，修筑质量不一，堤防存在渗漏、洞穴等隐患。采取防渗加固的主要方法有：钻探（锥探）灌浆加固，铺盖防渗，黏土截水槽，堤身临水侧筑前戗，央背水侧筑后戗，提防淤背，劈裂灌浆；利用土工合成，材料进行防渗加固；利用水泥土、混凝土材料进行防渗加固等。这些措施在实际应用中均取得了较好的效果。

Embankment Consolidation Measures

Acording to Statistics by the end of 1998, river levees and sea dykes in China amount to 258,000km in length. Because most of levees and dykes were constructed long time ago with different construction quality, there are many dangers of seepage, caves and so on. Main methods to control seepage and consolidate levees include grouting, blanket, clay cutoff wall, banquettes for both sides of embankment, split grouting, geo-textile, concrete and cement soil. Most of above -mentioned measures have achieved excellent effects in practice.
