电力线路跨越电气化铁路跨越架体材料和结构受力研究

Study on the Structural Forces and Materials of Power Line Crossing Electrified Railway Frame

电网、铁路同为国家重要的基础设施,近年随着铁路和电网建设的迅猛发展,电网电力线路与铁路的交叉跨越数量呈几何级爆发式增长态势,在跨越施工过程中,保障铁路运行安全极其重要。本文对电力线路跨越铁路跨越架的不同材料进行分析,对角钢类格构式跨越架、承插盘扣式跨越架的架体结构形式及受力仿真计算等进行研究,并提出使用建议。

Power grid and railways are both important national infrastructures,playing a vital role in economic development and ensuring people’s livelihood.With the rapid development of railway and power grid construction,the number of crossings between power lines in power grid and electrified railways has shown a geometric explosive growth trend.In the process of crossing construction,how to ensure the safety of railway operation is extremely important.This paper analyzes different materials of power line crossing electrified railway frame,researches the structural form and the force simulation calculation of angle steel lattice type crossing structure and disk lock steel crossing structure,and puts forward suggestions for use.
