研究目的:高速铁路客运专线车站多采用大跨度、钢结构无站台柱雨棚及高架站房结构,接触网系统作为车站建筑结构的重要组成部分,其支持悬挂结构直接影响站房景观的整体协调、美观性,需充分分析其结构受力和牵引供电需求,并结合现场实际进行优化布局。
研究结论:通过对已建高铁车站接触网景观结构布局分析,可以得出: 在确保安全、可靠性的前提下,从其系统的轻型化、局部屏蔽化、与建筑结构一体化等方面着手,可以通过接触网支持结构优化、附加导线设置、补偿及附属设施选型、站房接口布局、中心锚结优化,及其结构色彩搭配等关键控制点的方案优选,有效改善车站的整体景观效果,使其与周围环境有机融合,为铁路客站接触网结构优化设计提供借鉴依据。
Research purposes:The big span steel structure non - platform - column canopy and elevated station building structure are often used for the most stations of high - speed railway.The overhead contact system is an important part of the building structure of the station,and its suspended structure directly influences the overall coordination and aesthetics of the landscape of the station building.Therefore,it is necessary to optimize the layout of the overhead contact system according to the load bearing condition of the structure,the need of traction power supply and the real on - site situation.
Research conclusions:Based on the analysis of the layout of the landscape structure of the overhead contact system in the station of the high - speed railway and on the precise of ensuring the safety and reliability,the optimal schemes for the optimal support structure for the overhead contact system,installation of additional wire,selection of the compensation device and itssubsidiary facilities,interface layout of station building,optimization of the central anchor and color matching of the structure are presented from the areas of lightening the system,shielding some parts of the system and integration with the building structure to improve the overall landscape effect of the station and make the station landscape coordinated with the surrounding environment.This can provide the reference and basis to the similar works.
