摘　　要：向家坝升船机投入试通航后,由于金沙江下游河段实际航行的1000吨级船舶与升船机设计过机船舶主尺度匹配性差,船舶过机装载率较低。为进一步提高升船机通过能力及船舶运输经济效益,开展船舶过机吃水原型观测分析,逐步放开船舶过机吃水控制标准非常必要。通过大量过机船舶不同吃水、航速的进出厢试验原型观测,对影响过机船舶吃水控制标准的航道水位变幅、船厢水深变化,进出船厢航速、下沉量等因素进行系统的分析研究。结果表明,向家坝升船机过机船舶吃水提升至2.4 m,依然有30 cm以上的防触底安全富余量,满足船舶安全过机要求。After Xiangjiaba ship lift is put into trial navigation,due to the poor matching between the actual navigation of 1000 DWT ships in the lower reaches of Jinsha River and the main scale of the designed ship,the loading rate of the ship is low.To improve the traffic capacity of ship lift and the economic benefit of ship transportation,it is very necessary to carry out prototype observation of ship draught and gradually release the control standard of ship draught.Through prototype observations of entering and leaving the chamber of a large number of ships with different draughts and speeds,some factors about the draught control standard,such as the fluctuation of channel water level,water depth variation of ship chamber,speed and sinkage of ships entering and leaving the ship chamber,are systematically analyzed.The results show that there is still a safety clearance of more than 30 cm even if the ship draught is raised to 2.4 m.
