长江上游卵石急滩消滩水力指标研究

On Hydraulic Parameter of Rapids Abating of Pebble Rapids on the Upper Reaches of the Yangtze River

长江上游卵石急滩经过多次整治,仍然碍航,水力指标的不确定性是卵石急滩整治不成功的原因之一。根据交通部发布的长江上游的标准船型,采用理论计算和船模试验方法,对长江上游卵石急滩的水力指标作了研究。按照概化水槽的船模试验结果率定理论计算方法的计算参数,得到叙渝段标准船队消滩水力指标。

The indeterminacy of hydraulic parameter of the pebble rapids on the upper reaches of the Yangtze River is one of the reasons of failure in rapids regulation. According to the typical standard ship type for the upper reaches of the Yangtze River offered by the Ministry of Communications, and by theoretical means and ship model experiment, this paper studies the hydraulic parameter of the pebble rapids on the upper reaches of the Yangtze River. The hydraulic parameter of rapids abating obtained according to the calculative parameters experiment. of the pebble rapids on the upper reaches of the Yangtze River were acquired by the theoretical means that were validated by ship model experiment.
