接触网支柱挠度设计标准的探讨

介绍了国内外接触网支柱挠度设计标准的有关规定,分析了接触线横向偏移的组成因素,结合京沪高速铁路对支柱、腕臂结构、基础的位移进行计算,并对挠度组成及影响进行定量分析,提出了支柱挠度设计标准建议,按不同挠度标准对支柱进行了技术经济比较,为制定设计规范提供依据。

Discussion on Deflection Design Standard for OCS Mast

Introduces the relative regulations of deflection design standard of OCS mast home and abroad, analyzes the factors causing the contact wire lateral displacement, on basis of calculation of displacement of the mast, cantilever structure and foundation of Beijing-Shanghai high speed railway, implements a quantitative analysis for deflection composition and its influence, and puts forward a proposal of mast deflection design standard. The article also makes technically and economically the comparisons on masts under different deflection standard and these will offer the foundation on making the design specifications.
