倒运海水道整治工程斗朗—川槎大桥段实船适航试验

Experiment of actual ship seaworthiness test at Doulang-Chuancha Bridge section ofDaoyunhai waterway regulation project

为验证倒运海水道整治工程是否达到整治标准的通航要求,选取斗朗—川槎大桥段作为实船试验河段,采用该航段设计船型500吨级满载船作为试航船,进行实船适航试验。测量试验河段的水深地形、表面流速流向、航标配布和水位,试验船舶沿设计航线进行上下水航行,实时测量试航船舶航行轨迹、对岸航速、舵角、漂角、船舶与河岸之间的安全距离等航行指标及航行状态,并结合通航规范及标准,对整治后航道技术参数的合理性、航标配布的合理性等进行分析评价。结果表明,本试验航段的整治效果达到了整治标准的通航要求。研究成果可为类似工程提供参考。

In order to verify whether Daoyunhai waterway regulation project satisfies the navigation requirements of the regulation standards,we select the Doulang-Chuancha Bridge section as the experimental section,apply the 500 tons full load ship designed for this section as the trial ship to carry out the actual seaworthiness test.We measure the depth and topography,surface velocity and direction,navigation mark distribution and water level of the experimental section.We also measure the navigation indexes and navigation status of the test ship in real time,such as the navigation track,the speed of the opposite bank,the rudder angle,the drift angle,the safe distance between the ship and the bank when the test ship navigates up and down the designed route.According to the navigation rules and standards,we analyze and evaluate the rationality of the technical parameters and the distribution of navigation marks after the regulation.The results show that the regulation effect of this test section satisfies the navigation requirements of the regulation standard.The achievement can provide references for the similar projects.
