基于PIANC的码头前沿波浪富裕深度分析

Analysis of wave response allowance alongside jetty apron based on PIANC

PIANC提出了从船舶等级、船舶装载度、水深、波高、浪向和航速共6个影响因素分析计算港池和航道的水域波浪富裕深度。针对码头前沿波浪富裕深度,引入了PIANC关于波浪富裕深度的计算方法。并详细分析了PIANC关于码头前沿波浪富裕深度的计算方法的适应性,简要探讨了长周期波浪引起的船舶垂直运动量。重点对PIANC计算方法进行简化,并与中国规范进行了对比分析,对PIANC计算方法简化后的码头前沿波浪富裕系数K0取值提供了建议,为工程相关设计提供参考。

PIANC proposed the calculation of the depth of wave richness in the harbor basin and channel from the analysis of six influencing factors including ship class,ship loading degree,water depth,wave height,wave direction and navigation speed.Aiming at the depth of wave richness at the front of the wharf,PIANC's calculation method of wave richness was introduced.In addition,the adaptability of PIANC’s calculation method for the depth of wave wealth at the wharf's front edge is analyzed in detail,and the vertical motion of ships caused by long period waves is briefly discussed.This paper focuses on the simplification of the PIANC calculation method and the comparative analysis with the Chinese code,and provides suggestions on the wave response allowance alongside jetty apron coefficient K0 after the simplification of the PIANC calculation method,providing reference for the engineering design.
