上跨电气化铁路防护方案比选及施工技术的应用

Selection of Railway Protection Schemes for Upper Span Electrification and Construction Technology

近些年来,随着国内扩大内需对铁路建设加大了投入,越来越多的铁路需要上跨河流、公路、铁路等施工,跨越既有铁路线对既有铁路行车安全形成了很大的影响,本文针对重载铁路跨越既有电气化铁路的防护方案选取及对应施工技术进行阐述,希望能对类似工程的施工提供一些帮助。

With the increasing investment in railway construction in China, more and more railways need to cross rivers, highways,railways and other existing railways, which has a great impact on the safety of existing railways. In this paper, the selection of protection schemes and construction technology for heavy-haul railways across existing electrified railways are described, hoping to provide some assistance in the construction of similar projects.
