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。 This paper introduces the relevant provisions of the design criteria for the deflection of the catenary struts at home and abroad, analyzes the compositional factors of the horizontal displacement of the contact line, calculates the displacement of the pillar, arm structure and foundation with the Beijing-Shanghai high-speed railway, and makes the deflection composition and influence Based on the quantitative analysis, the proposition of the design criteria for the deflection of the pillars is put forward. The technical and economic comparisons of the pillars are carried out according to different deflection standards, which provides the basis for the design of the design code.
