葛洲坝工程的通航建筑物规模较大,技术复杂。建坝后,枢纽水头低,库容小,仍然保持着原天然河道的特性。因此,在通航建筑物设计中,遇到最突出的问题,就是枢纽上下游航道的泥沙淤积和复杂的水流条件。为了解决这两个问题,保证长江航运安全畅通,经过反复调查和科学试验,决定采用人工防淤堤、冲沙闸及其他辅助工程措施,以“静水通航,动水冲沙”的办法,作为解决葛洲坝工程坝区引航道的泥沙淤积和改善通航水流条件的基本途径。通过几年来的泥沙、水工、船模等试验结果表明,采用这些措施建成的葛洲坝一期工程的三江航道,是一条通航条件良好的静水人工航渠。航道的泥沙淤积问题,基本得到解决。
Gezhouba project navigation buildings larger, complex technology. After the dam was built, the head of the junction was low with a small storage capacity and still maintained the characteristics of the original natural river. Therefore, the most prominent problem encountered in the design of navigable buildings is the sedimentation and complicated flow conditions of the upper and lower reaches of the hub. In order to solve these two problems and ensure the safe and smooth shipping of the Yangtze River, after repeated investigations and scientific experiments, it was decided to adopt artificial anti-bank breakage, red sand sluice gates and other auxiliary engineering measures to adopt the method of " Gezhouba dam project to address the sediment deposition and navigation channel to improve the conditions of the basic ways. Through several years of sediment, hydraulic engineering, ship model test results show that the use of these measures to build the Gezhouba Phase III Project Sanjiang channel, is a well-navigable hydrostatic artificial navigation channel. The sediment deposition in the channel has basically been solved.
