南水北调中线总干渠白河倒虹吸水毁修复设计探讨

Discussion on the Design of Remediation for Baihe River Inverted Siphon Water Damage in the Middle Route of the South-to-North Water Diversion Project

文章针对白河倒虹吸水毁状况和水毁成因,结合砂砾石河床地质条件,提出了对倒虹吸管身段上游垂直和水平防护、顶部防护、下游消力池、末端护坦和防冲槽工程修复防护措施以及对河道两岸采用坡式护岸工程的防护设计,解决了水毁修复和主槽防护设计技术方案难题,得到了较好的效果,可供相关单位对类似工程防护设计时参考。

This paper addresses the condition and causes of the water damage to Baihe River inverted siphon and takes into account the geological conditions of the gravel riverbed.It proposes protective measures for the upstream vertical and horizontal protection,top protection,downstream energy dissipation pool,end protection platform,and erosion-resistant groove engineering restoration,as well as protective design for sloping revetments on both sides of the river channel.These measures successfully address the challenges of water damage repair and main channel protection design,yielding positive results.They can serve as a reference for relevant units when designing protective measures for similar projects.
