基于英国标准的系缆墩设计探讨

Discussion on Design of Mooring Dolphin Based on British Standard

基于具体的工程实例,本文阐述了基于英国标准的系缆力计算方法及流程,包括风荷载的计算、水流力的计算以及单根缆绳最大系缆力的计算,从而确定系缆设施规格。在系缆力计算的基础上,进一步分析了基于英国标准设计系缆墩时需要考虑的各种不同工况,并与中国标准的计算要求进行了对比分析。英国标准与中国标准的对比结果显示,英国标准计算得到的最大系缆力数值较中国标准大、英国标准对位移控制的要求较为严格。本文研究可为国外港口工程系缆墩的设计提供一定借鉴。

Based on actual projects,BS Standard-based calculation method and process of mooring force are described in detail,including the calculation of wind load,water current force and the maximum mooring force of a single cable,which produces the specifications of mooring facilities.The mooring force calculation results are used to analyze various working conditions that need to be considered in the design of mooring dolphin based on British standard,which also compare with the calculation requirements based on Chinese standard.The comparison results show that the maximum mooring force calculated as per British Standard is larger than that stipulated in Chinese Standard,and British Standard has stricter requirements on the control of displacement.This research can provide a certain reference for the design of mooring dolphin in oversea ports.
