摘　　要：文章通过优化汉江雅口航运枢纽一期导流围堰防渗体系的设计及施工,加快了围堰防渗体系的建设进度,在枯水期过半的情况下成功完成了一期围堰的施工。优化后的复合土工膜防渗墙联合防渗体系也成功应用在了二期导流围堰中,一期、二期导流围堰分别度过了2017年、2021年汉江特大秋汛,围堰未发生明显渗漏破坏,充分证明了防渗体系优化设计的合理性,验证了复合土工膜防渗墙联合防渗体系的可靠性,为类似围堰工程防渗体系的设计及施工提供了参考。By optimizing the design and construction of the seepage prevention system for the Phase Ⅰ diversion cofferdam of the Hanjiang Yakou Navigation Hub,the construction progress of the cofferdam's seepage prevention system was accelerated.Despite completing construction during the latter half of the dry season,the Phase Ⅰ cofferdam was successfully built.The optimized composite geomembrane and seepage prevention wall combined seepage prevention system was also successfully applied to the Phase Ⅱ diversion cofferdam.Both Phase Ⅰ and Phase Ⅱ cofferdams withstood the major autumn floods of the Hanjiang River in 2017 and 2021,respectively,without significant seepage or failure,fully demonstrating the rationality of the optimized seepage prevention system design.This also validated the reliability of the composite geomembrane and seepage prevention wall combined seepage prevention system,providing valuable reference for the design and construction of seepage prevention systems in similar cofferdam projects.
