摘　　要：对常用的几种架空线路接触网支柱基础进行了对比分析,结合青岛市城阳区现代有轨电车示范线工程,从基础的特点、抗倾覆承载力、路基结构、管线、地质条件、场地条件、施工工序、造价等方面分析比较,探讨了有轨电车接触网支柱基础选型的控制因素。支柱基础选型时应充分利用现场条件,正线上支柱基础宜选择扩展基础,路口软横跨支柱基础宜选择桩基础。本工程充分利用岩石的承载力,创新性采用岩石锚杆基础,希望能为类似工程提供一定的参考。Compare and analyze several overhead catenary support foundations that are used commonly.A few aspects about foundation features,anti-overturning bearing capacity,subgrade structure,pipelines,geology,site conditions,construction procedure,costs are analyzed and compared,combined with modern tram in Chengyang District of Qingdao City.The controlling factors of overhead catenary support foundation selection are discussed.The on-site conditions should be fully utilized for support foundation selection,extension foundation should be adopted for support foundation on the main line,and pile foundation should be adopted for support foundation of soft crossing at intersections.The bearing capacity of rocks is fully utilized in this project,so that rock anchor foundation is innovatively adopted,hoping to provide some references for similar projects.
