基于最大横流累积频率的航道宽度设计方法

Design method of approach channel width under maximum guaranteed cross flow rate

针对以往航道宽度设计中横流设计值选取原则不明确的问题,应用涨潮潮差与航道最大横流的线性关系推求航道最大横流的累积频率曲线,提出了基于最大横流累积频率的航道宽度设计方法,从航道横流特征、船舶进出港特点讨论了设计标准的选取原则。研究结果表明：对于连云港航道,综合考虑航道横流特征及船舶进出港特点,可取最大横流累积频率40%∽50%。

For the ambiguous selection principles of cross flow design value during the channel width design in the past, we used the linear relation of flood tidal range and maximum cross flow to obtain the cumulative frequency curve of the maximum cross flow along channel, put forward the channel width design method based on cross flow assurance rate, and discussed the selection principles of design standard from cross flow characteristics and the ship navigation features. The results show that： for the channel of Lianyungang Port, the maximum guaranteed cross flow rate of 40 %∽50 % can be obtained by considering the cross flow characteristics and the ship navigation features.
