摘 要:采用数学模型和船舶操纵模拟试验的手段,分析库区急弯航道在枢纽低水位运行工况下的碍航特性,研究采用优化航行方案和调整待闸锚地位置等措施改善通航条件。结果表明,利用码头岭急弯段凹岸的大范围缓流区,采用船舶入弯后先沿右岸驶入缓流区,降速转向后出弯驶向下游的航行方案,可显著降低船舶过弯的横移速度和漂移量;将锚地由闸前调整至弯顶缓流区,船舶抛锚靠泊所需的回旋水域明显减小,横移速度仅为0.4m/s,起锚进闸的操纵风险也较低。上述非工程措施对保障库区急弯段的通航安全有积极作用。By means of mathematical model and ship handling simulation test,we analyze the navigation obstruction characteristics of the sharp bend channel in the reservoir area under the operation condition of low water level of the pivot,and improve the navigable conditions by optimizing the navigation scheme and adjusting the position of the anchorage.The results show that the ship’s traverse speed and drift can be significantly reduced by taking advantage of the large range of slow flow zone in the concave bank of the Matouling sharp bend section,and adopting the navigation scheme that the ship enters the slow flow zone along the right bank first,turns down and then leaves for the downstream.When the anchorage is adjusted from the front of the lock to the slow flow zone at the top of the bend,the circumferential water required for anchoring is significantly reduced,the traverse speed is only 0.4 m/s,and the maneuvering risk of lifting anchor into the lock is also lower.The above non-engineering measures play a positive role in ensuring the navigation safety of the sharp bend section.
