摘　　要：介绍了施工通航泥沙模型的研究成果，包括施工期坝区河段冲淤变化规律、临时船闸引航道泥沙淤积形态、淤积分布、淤面标高、回淤速度、碍航淤积量、淤沙级配以及淤积对明渠和临时船闸通航条件的影响等，并提出了相应的改善措施。This paper introduces some resarch results on sediment model experiment of navigation in the course of construction. including the laws of erosion and deposit change of sediment in dam area,depositional configuration of sediment in the approaches of temporal ship lock, distribution and surface sea-level of deposition,speed of return deposition, volume of deposition of frustrating navigation, grain grade of deposition and the effect of deposition on navigable condition in open channel and temporal ship lock and so on. Some measures of amelioration are presented,which have important value to the construction of the project.
