对港口工程技术规范的《河港总体及工艺设计》(以下简称“总规”)中码头前沿高程的设计标准(年最高水位频率)取值问题,存在着以下几种论点: 1.前沿高程可采用非稀遇洪水的设计标准,其实质是允许码头一定程度的淹没(特别是标准低的中小码头),即允许码头的短期淹没;这意味着装卸作业的暂时中止,一俟洪水 There are several arguments as follows on the design value of the front elevation of the wharf in the “port overall and process design” (hereinafter referred to as the “general rules”) of port engineering specifications: 1. The front elevation can be The design criteria for non-infrequent floods, in essence, allow a certain degree of submergence of the terminal (in particular of a standard low-level terminal), allowing short-term submergence of the terminal; this means temporary suspension of loading and unloading,
