In the design of mast support structure, stress analysis, selection and mast foundation must cooperate with roadbed, station yard and so on. It shall make the conformation form and parameter setting of OCS to meet the mechanical requirements, convenient installation and operation. This paper listed the common types of OCS mast, and compared the actual situation and detail costs. It was concluded that transverse pre-stress steel reinforced concrete mast and cup-type foundation should be recommended to reconstructed railway construction.%在接触网支持结构设计中，接触网支柱受力分析、选型及基础设计环节，都必须与路基、站场等专业密切协作配合，以使接触网支柱构造形式及基础设置，能够满足运营当中实际受力要求、施工方便、安装简单，还能够使上述各专业间在施工实施过程中达到同步及协调统一。本文列举了常用的路基段接触网支柱基础型式，结合实际情况，通过详细技术经济的比较，得出了广大线路基段宜采用横腹式钢筋混凝土支柱、杯形基础的结论。
