摘　　要：近年，位山灌区为适应小浪底水利枢纽运行以来新的引水条件，满足跨省调水任务及改善输沉区泥沙环境要求，逐步摸索试验性应用通道输沙方法，减轻输沉区泥沙处理负担。对以挖待沉传统空池清淤方式及近3年来试验应用通道输沙方式的效果进行系统观测分析。说明传统方式清淤时机偏保守，空库清淤量大及堆沙环境影响大，清淤负担及二次治理负担沉重，且具有清淤量越大回淤量亦越大特点，输沉区不堪重负。通道输沙方式，沉沙池使用时间长，清淤量小且无池外弃沙，回淤量小，适当维护可保持输水输沙条件，整体减沙运行效果十分明显。In recent years, Weishan Irrigation Area are exploring the application of channel sediment test methods to reduce sediment treating burden step to step, to adapt the new condition after the operation of Xiaolangdi Dam to fulfill the inter-provincial water transfer tasks and improve the sediment transport environment. It observes and analyzes systematically the traditional dredging methods and the effect of the channel sediment transportation application in the last 3 years. The result shows that the traditional dredging way is conservative, with large impact on environment and heavy sediment treating burden. But with the channel sediment transportation way, we can use the sand basin for a long time, with no sediment deposited. If properly maintained, it can keep the water and sediment transportation condition. As a whole, it has very obvious effect in reducing sediment.
