在港口工程技术规范(下称新规范),第一篇第一册《海港总体及工艺设计》中规定海港码头前沿的设计水深公式为D=T+Z_1+Z_2+Z_3+Z_4(符号的具体内容见新规范第33页)。该式基本上是引用了1960年港口工程设计标准及技术规范(下称60年规范)中港口水域及航道水深公式:H=T+Z_1+Z_2+Z_3+Z_4的形式(符号内容见60年规范第8页)。所不同的是将Z_3航速超深部分改为船舶配载不均匀而增加的船尾吃水值。多年来,我院承担的许多新
In the Technical Specifications for Port Works (hereinafter referred to as “the new code”) and Part I, “Harbor General and Process Design”, the design depth of the front of a harbor terminal is D = T + Z_1 + Z_2 + Z_3 + Z_4 See the new specification page 33). This formula basically refers to the formula of port water area and waterway depth in 1960 Port Engineering Design Standard and Technical Specification (hereinafter referred to as “60-year Specification”): H = T + Z_1 + Z_2 + Z_3 + Z_4 Specification page 8). The difference is that the ultra-deep part of the speed of Z_3 will be replaced by an increase of the draft value of the stern of the ship after being loaded with the ship. Over the years, our hospital has undertaken many new
