摘要
针对枢纽船闸口门外连接段航道,在纵向流速2.5m/s、水面比降0.2‰,以及船队在静水航速3.0m/s的条件下,分析船队推轮推力与水流阻力的关系,提出船队排水量与推轮功率比值应满足≤9.52t/kW的要求。
Under the condition that lengthway＇s current velocity is 2.5 m/s, surface gradient is 0.2‰ and slack-water ship speed is 3.0 m/s, the relationship between current resistance and thrust push of the push tug at the transitional reach outside entrance of navigation lock is analyzed, and the requirement that the ratio of displacement tonnage to power should be less than 9.52 t/kW is put forward.
