摘　　要：接触网作为电气化铁路的大动脉,由于其露天和无备用架设,当发生自然灾害时易受到破坏而影响线路安全运行。南昆铁路诸多区段地处山区,因地势起伏大且地质条件极为复杂,给遭受自然灾害侵袭后的接触网复旧增添了难度。本文以南昆铁路汪甸站接触网水害复旧为例,结合现场实际情况和复旧难点,对提出的4套复旧方案进行比选,确定最优方案,讨论了该方案的实施思路和重要项点的工程计算,并对类似接触网复旧提出参考建议。As the main artery of electrified railway,OCL is liable to be suffered from the damage when the natural disaster happens because it is set in the open air without any stand-by facility.Many sections of the Nanning-Kunming railway are located in mountainous areas,which increase the difficulty in reconstructing the OCL after it is suffered from the natural disasters due to greatly undulate terrain and extremely complicated geological conditions.In this paper,taking the restoration of the OCL after suffered from the flood disaster in Wangdian station of Nanning-kunming railway as an example,combined with the actual situation at site and the analysis of the difficulties in its restoration,four schemes are compared from multiple aspects,and finally the fourth scheme is selected.The paper also discusses the fourth scheme’s implementation ideas and engineering calculations of important links,and gives some suggestions and references on OCL restoration.
