摘　　要：通过对龙滩水电枢纽两级升船机中间渠道内航行条件的水工模型试验研究,结果表明:中间渠道内船舶(队)单向航行速度小于2.0 m/s时,船行波、航行阻力和船体下沉量均不大;中间渠道直线段宽为32 m时,宜采用航、停的会让方式,航速应<1.5 m/s,而船舶宜停泊在右航线上;船舶(队)转弯时的航迹带要宽,因此不应有转弯段等航速会船。From hydraulic model test on navigable condition in the intermediate channel between the two ship lifts of Longtan Power Station, it＇s shown that the ship wave, ship sinkage and ship sailing resistance is not large, when the sailing velocity in one way is less than 2.0 m/s. When the intermediate channel is 32 m wide, one ship should be halted on the fight sailing line if another ship is passing by and the sailing velocity should be less than 1.5 m/s. The width of sailing track is large in the incurvate channel, so ships should not pass by each other with constant sailing velocity in this part.
