摘　　要：随着中国铁路事业高速发展,铁路干线的普速道岔已无法满足运输能力的需求。于是,普速铁路需进行提速改造和高速铁路对接,在改造的过渡期,高速道岔的插入是整个既有线提速改造的重中之重,因此,论文阐述了韩原铁路正线(160 km/h无缝线路)上插入高速道岔施工过程中的经验,以供同类工程借鉴。With the rapid development of China’s railway industry, the common speed turnout of the main railway line has been unable to meet the demand of transportation capacity. Therefore, the ordinary speed railway needs to be upgraded and connected with the high-speed railway. In the transition period of the renovation, the insertion of high-speed turnout is the most important part of the whole existing railway. Therefore, the paper expounds the experience in the construction process of inserting high-speed turnout on the main line(160 km/h jointless track) of Hanyuan railway for reference of similar projects.
