Abstract

Abstract

In order to directly define the hydraulic parameter of rapids abating, power method was suggested according to the comparison of ship effective power and water flow power in rapids reach, and was verified by theoretic analysis and the test data of remote-control model while ship ascending rapid in generalized rapids reach.It is pointed that ship effective power was larger than water flow power while ascending rapid, the difference range increases with the sailing speed of opposite bank; while ship failed to ascend rapid, ship effective power was lower than water flow power.Analysis result shows that the method can directly determine the hydraulic parameter of rapids abating according to hydraulic conditions and the performance data of different ship types, can satisfy the future design of waterway development, and may be applied in the regulation design of rapids channel.
