土工织物在河岸反滤体施工中的应用

Application of Geotextile in Construction of Riverbank Filter Body

以位于双台子区盘锦大桥~双台子大桥之间、长1 100 m的双台子区城市段河道疏浚治理工程为例,结合工程河岸坝坡各土层岩性渗透情况,进行了土工织物应用于河岸反滤体中的主要技术方法及应用要求的分析探讨,并总结了土工织物作为新材料、新技术在岩土工程土料填筑、反滤层设计及施工中的应用要点。结果表明,土工织物在性能稳定性、质量、造价、施工便捷程度、经济性等方面均比常规的砂石反滤料优越,其在岩土工程防渗反滤方面具有广阔的应用前景。

Taking the dredging project in urban section of Shuangtaizi District, which is located between Panjin Bridge and Shuangtaizi Bridge in Shuangtaizi District, with a length of 1,100m, as an example, combined with the lithologic permeability of each soil layer of the bank slope of the project, the main technical methods and application requirements of geotextile applied in riverbank filter are analyzed and discussed. The application points of geotextile as new material and new technology in filling of geotechnical engineering soil, design and construction of filter layer are summarized. The results show that the geotextile is superior to the conventional sand and stone filter material in terms of stability, quality, cost, construction convenience and economy, and has broad application prospect in the field of seepage prevention and filtration in geotechnical engineering.
