摘要
针对国内接触网后锚固技术发展现状,通过分析比较后锚固设计依据、锚固区混凝土基材受力判断、锚栓类型选择和锚栓受力计算,提出了在接触网后锚固设计中,标准应用、开裂混凝土判定、锚栓选择的原则,以及接触网在桥隧不同锚固区采用的计算方法和建议措施,供今后混凝土结构后锚固工程设计和施工参考。
Based on the development of post-installed fastenings technology of overhead catenary system(OCS)in China,this paper analyses,for the first time,a standard principle for the design of post-installed fastening,for the detection of the crack concrete area and the selection of anchor types,meanwhile introduces the post-installed fastenings calculation method and the related proposals for OCS in the tunnel and bridge.This study has a potential value for the engineering design and construction in the near future.
