新建铁路穿越特高压输电线走廊增设防护棚洞方案探讨

Discussion on Scheme for Protection Shed Added on Newly Constructed Railway Line Passing through Power Transmission Line Corridor

针对新建电气化铁路三电迁改工程复杂、费用高、协调难度大、影响铁路运输安全等问题,提出在输电线路走廊下方增设防护棚洞方案,介绍了防护棚洞设计思路、结构选型、结构设计及其他相关设计,为新建电气化铁路电力迁改模式提供了新思路。

With regard to the problems of complicated reconstruction,higher costs and difficult coordination for demolition of electrified railway's communication lines,broadcasting&television lines and electric power transmission lines that may induce impact to the railway transportation safety,the paper puts forward a scheme for adding of protection shed under the electric power transmission line,introduces the thoughts of design,selection of structure,structure design of the protection shed added under the power transmission line and other relative design,providing a new way of thoughts for mode of electric power transmission line demolition for newly constructed electrified railway.
