摘　　要：结合唐山中低速磁浮试验线上更换钢铝复合接触轨工程的实践,对工字形接触轨绝缘侧向安装、轨道梁和车辆限界和接触轨在道岔梁的过渡方案进行分析研究;介绍了工程实施重点、实施步骤、接触轨系统新产品(钢铝复合接触轨、道岔梁处接触轨过渡关节弯头和膨胀接头)的技术功能以及施工的技术配合。最终取得了圆满成功,为我国中低速磁悬浮线路建设积累了经验。Taking into consideration of the mid and low-speed maglev test line in Tangshan to replace the steel-aluminum contact rail engineering practice,the paper analyzes the contact rail-shaped insulating lateral installation,track beam and vehicle clearance and contact rail in the transition of the turnout beam;and it describes the implementation of the project key points,implementation steps,and new products（steel-aluminum contact rail,the joint bends for turnout beam at the contact rail transition section and expansion joints）,technical features and complete construction technology.The final success is a complete satisfactory for mid and low-speed maglev line construction in China and provides accumulated experience.
