摘　　要：河道开挖施工中经常遇到粉质壤土或粉质砂壤土(俗称粉砂土),一直是河道开挖和河道成形的"绊脚石"。淮安市古黄河水利枢纽工程导流河开挖成功地克服了粉砂土施工难点,对今后类似工程起到借鉴作用。粉砂性土质河道开挖施工时,明沟降排水和挖掘机接力开挖翻晒、倒运等施工措施,具有见效快、可分段同时施工、流水作业等特点。Channel excavations frequently encounter silty loam or silty sandy loam （commonly known as silty sand）, which has been a ＂stumbling block＂ to channel excavation and channel forming. The Huaian Ancient Yellow River Water Conservancy Project diversion river excavations successfully overcome silty sand construction difficulties, and will play a reference for similar projects in the future. In the process of silty soil channel excavation, the construction measures such as drainage through open trench and dry soils by plowing and aerating and transfer using excavators, have effective and time saving advantages.
