摘要港珠澳大桥是一座世界级跨海大桥，其沿线的采样点区域均属于强雷区，雷击风险大，因港珠澳大桥项目将于2017年竣工，其防雷装置检测、维护等工作方案正在研究设计当中。文章结合港珠澳大桥的桥梁结构特性、水文气象条件，首次提出跨海大桥高架桥墩、钢箱桥面及桥面上不同金属系统接地电阻估算模型，为港珠澳大桥桥面配备的各通信、配电及重点防护系统的雷电防护提供参考。

Abstract：Hong Kong-Zhuhai-Macao Bridge is a world-class cross-sea bridge and its sampling areas all belong to heavy mine fields with high risk of lightning stroke.The Hong Kong-Zhuhai-Macao Bridge is expected to be completed in 2017.Its lightning protection device and maintenance are being researched and designed.By connecting the bright structure characteristics and the hydrology-weather condition of the Hong Kong-Zhuhai-Macao Bridge,this paper has proposed the bridge pier,steel box bridge floor and the ground resistance estimation models of the different metal systems on the bridge floor,which can provide references to the communication,power and the lightning protection for the key protection systems.

Key words： Hong Kong-Zhuhai-Macao Bridge resistance resistivity bridge
