地铁车站及区间防雷接地设计简析

Brief Analysis on Protection against Lightning and Earthing Design of Metro Station and Section

根据现行技术规范的要求和工程实践,结合某轨道交通3、4号线,某地铁11号线工程,阐述地铁车站(地下车站、高架车站)、高架区间的防雷接地的主要设计思路,总结出一些适用于地铁工程防雷设计的要点,主要包括:①地下车站的接地网设置;②地下车站的防雷设计;③高架车站的接地网设置;④高架车站的防雷设计;⑤高架区间的防雷设计。

According to the requirements and engineering practice of the current technical specifications,combined with a Rail Transit Line 3 and Line 4,a Metro Line 11,the main design ideas of protection against lightning and earthing in metro station(underground station,elevated station)and elevated section are expounded,and some key points suitable for protection against lightning design of metro engineering are summarized,including:①earthing grid setting of underground station;②protection against lightning design of underground station;③earthing grid setting of elevated station;④protection against lightning design of elevated station;⑤protection against lightning design of elevated section.
