摘　　要：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。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.
