摘　　要：针对电气化铁路低净空跨线桥下接触网不能正常通过的情况,提出了一种用于多支承力索下锚的特殊硬横跨结构,对该结构的受力情况进行了有限元仿真分析,并通过实际工程验证了该结构的可靠性。A special portal structure for anchoring of multiple messenger wires is proposed with regard to that the OCS of electrified railway is unable to negotiate through the overpass bridge with low clearance.The finite element simulation and analysis is used for analysis of the structure stress,and the reliability of the structure is verified in the actual projects.

关 键 词：低净空 接触网 硬横跨 仿真分析
