摘　　要：三峡-葛洲坝两坝间河段是川江船舶航行最困难的航段之一。研究在该航段航行的3种船型在泄洪期安全上水过滩的通航能力,分析计算相关船型在各种流量流速条件下安全上水过滩应具备的对水航速和对岸航速,总结出两坝间河段最危险的航段,为船舶安全上水过滩和有关部门制定船舶安全通行的政策和限制政策提供依据。The reach between Three Gorges Dam and Gezhouba Dam is the part most difficult for shipping in Chuanjiang River.This paper studies the navigation capacity of three types of ships during the discharge.Through calculating and analyzing the proper ships′ velocities relative to both the current and the bank under various discharges and flow speeds,we generalized the most difficult leg between the Three Gorges and Gezhouba,so as to provide important references for safe navigation passing through the reach.
