摘要
高铁跨越架是一种能迅速搭建的跨越高速铁路的金属支架体。目前,高速铁路跨越施工尚无国家或行业规范,设计时无标准可遵循。以某高铁跨越架结构为背景,对跨越架结构设计中存在的若干关键问题进行深入研究。讨论了高铁跨越架分析中风荷载计算方法,给出了断线荷载模拟建议,并对现有跨越架的整体稳定分析方法进行研究,提出一种简便的计算方法。研究内容可为送电线路安全、高效地跨越高速铁路提供技术保证。
The crossing frame structure for high-speed railway is a kind of metal frame which can be quickly assembled to cross the high-speed railway. Currently, for the high-speed railway crossing construction, there are no national or industrial standards to follow in design. Taking a crossing frame structure for high-speed railway as the background, several key problems in the design of the crossing frame structures were investigated. Wind load calculating method in analysis of crossing frame structure for high-speed railway was discussed and recommendations on simulation of broken wire load were provided. Overall stability analysis method for current crossing frame structure was studied and a simplified calculating method was given. Research contents can provide technical insurance for safe and highly efficient crossing of transmission line over high-speed railway.
