| 摘 要： | 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。

| Abstract: | In order to investigate the widening value in bending section of canal, the layout of widening section in curved channel, computing formula of AB and the influencing factors were analyzed in this paper. It can be seen from the results of analysis that the major factors effecting the widening value in bending section are bend radius, length of ships （fleets）and width of channel. According to the empirical formulas under various conditions, the widening value △B was calculated. After comparison of each computation result, the formula of calculation of recommended width is proposed. |
