防波堤口门有效宽度研究

关于防波堤口门有效宽度,现行规范有明确的定义,对其具体尺度也有明确的要求。但近年来随着船舶的大型化,部分已有口门的有效宽度已经不满足规范规定的通航要求,而实践表明,在一定的航行条件下,口门有效宽度适当减小,是能够满足安全通航要求的。研究口门有效宽度的相关规定和影响口门有效宽度的主要因素,结合工程实例,对口门有效宽度的确定方法提出建议。

Effective width of breakwater entrance

The effective width of breakwater entrance and its dimensions are clearly defined in the current design code. However, with the enlargement of ships, some existing breakwater entrances can hardly meet the code-specified navigation requirements. Furthermore, the practice shows that, under some certain sailing conditions, the appropriately reduced effective width of breakwater entrance is able to meet the requirements of safe navigation. On the basis of a project instance, this paper studies relevant specifications and main impact factors of effective width of breakwater entrance, and gives some proposals on methods for determining the effective width of breakwater entrance.
