摘要: 根据工程细颗粒淤积泥沙的特点,结合沿程均匀管道泄流理论,提出了运用沿程清淤廊道解决工程泥沙淤积问题的设想。简述了沿程清淤廊道结构、运用方式和措施优点,并对措施可能出现的问题简要地提出了解决办法;简要介绍了已有类似措施在工程中的应用。经深入研究证明沿程清淤廊道具有较好的适用性,该措施可在航道、水库、电站、船闸等水利工程的防淤、清淤中发挥重要的作用。

Abstract: According to the characteristics of fine-grained depositing sediment, and in association with the theory of flow along pipeline with uniform draw-off, the solution of engineering sediment problem by using desilting corridor along the path is proposed. The structure, operational mode, and advantages of the desilting corridor are described, and a solution for potential problems is put forward. Similar methods in engineering application are briefly introduced. If further studies and the following results could prove that the desilting corridor has good applicability, the measure could be an important desilting approach in waterways, reservoirs, power plants, ship locks and other hydraulic projects.

Key words: desilting corridor along the path, desilting hole, sediment deposition, waterhead, pump station
