为研究限制性航道弯曲段的航道加宽值问题,分别对弯曲航道加宽处的平面布置,加宽值ΔB的计算公式以及加宽值的影响因素等进行分析。通过对船舶(队)在弯道段航行所受影响因素进行分析,得出影响弯曲航道加宽值的主要因素为弯曲半径、船舶(队)长度及航道宽度。按照各种运行条件下提出的弯道加宽值的经验公式,对加宽值ΔB进行计算。通过比较各公式的计算结果,提出了推荐加宽值的计算公式。
In order to study the problem of channel widening value in the curved section of the restricted channel, the paper analyzes the plane layout of broadening bend, the formula of widening ΔB and the influencing factors of widening value. By analyzing the influencing factors of the sailing of the ship in the curved section, the main factors that affect the widening value of the curved channel are the bending radius, the length of the ship and the width of the waterway. The widening value ΔB is calculated according to the empirical formula of curve widening value under various operating conditions. By comparing the calculation results of each formula, the calculation formula of recommended widening value is proposed.
