Abstract: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:① earthing grid setting of underground station;② protection against lightning design of underground station;
③ earthing grid setting of elevated station;④ protection against lightning design of elevated station;⑤ protection against lightning design of elevated section.
Key words:metro station;elevated section;protection against lightning and earthing;natural earthing body;artificial integrated earthing grid;equipotential bonding;protection against lightning downlead;stray current
