直墙式码头前沿顶高程计算方法

中国港口工程设计规范中码头面高程可按上水标准确定直墙式码头前沿顶高程。而在英美等国外设计标准中,提出码头面高程应考虑设计水位、装卸设备安全作业、淹没程度等因素,综合分析确定码头面高程,其中码头面受淹没的影响程度应为主要考虑因素。以平均越浪量作为码头面淹没影响程度判断标准,介绍码头前沿平均越浪量的计算方法,并依此提出直墙式码头面高程计算方法,同时与国内外规范中的计算方法进行比较分析。该方法对同类别的码头设计具有实际参考意义,同时对码头使用营运安全标准的把控也有参考意义。

Calculation method of vertical wall wharf deck elevation

Vertical wall wharf deck elevation can be determined according to the flood degree in the Chinese standard.However,in the design standards of Britain,America and other foreign countries,it is proposed that the design water level,safe operation of loading and unloading equipment,and the degree of submergence should be taken into account in the elevation of wharf surface.Among them,the degree of inundation of wharf surface should be the main factor to be considered.This paper takes the mean overtopping discharge as the criterion for classifying the degree of inundation of wharf surface,and introduces calculation of the mean overtopping discharge.Based on this,the calculation method of vertical wall wharf deck elevation is proposed and compared with the calculation methods in domestic and foreign codes.This method has practical reference significance for wharf design of the same kind and also for the control of operation safety standard of wharf.
