摘　　要：分析了公路隧道防雷接地的特殊性 ,提出将隧道初期支护的锚杆、管棚、拱架等焊接固连起来多点引出做基础接地体 ,构成接地装置 ,并采用拦截、屏蔽、均压 (等电位连接 )、分流和共用接地系统等综合防雷方案。实践证明 ,行之有效 ,对公路隧道防雷接地具有现实意义。On the basis of analyzing the characteristics of lingtning protection and earthing system for hingway tunnels,it is proposed that earthing electrode is composed of the metals of initial support in tunnel such as anchor rods,long-pipe-shed,reinforcing steel net and so on. An overall lightning protection scheme is adopted,inclusive of air-termination system,shield,equipotential bond,parallel branch and common earthing system. The experimental results prove that this scheme is effective,it has practical significance in lightning protection and earthing system for highway tunnels.
