摘　　要：充水式橡胶坝的应用日益广泛使用,其集水廊道失效现象逐渐增多。对砂性河道上充水橡胶坝集水廊道的失效原因进行了分析,提出了改进措施,并以太湖县长河水环境整治工程3^(#)拦河堰为例,详细介绍了在无砂混凝土集水廊道的基础上增加斜插反滤进水管的改进设计,并通过渗流计算验证了改进结构的可行性和可靠性。相关成果可为类似工程提供借鉴。Water-filled rubber dams have seen widespread use while the failures of their water collection gallery are also gradually increasing.This study examines the failure causes of the water collecting gallery of waterfilled rubber dam on sandy soil river and offers improvement measures.Additionally,taking the water environment improvement project at No.3 weir of Changhe River in Taihu County as a case study,we present a design of adding an inclined anti-filter inlet pipe to the existing sand-free concrete water collecting gallery,and verify the feasibility and reliability of this improved structure through seepage calculation.The findings provide references for similar projects.
