Abstract：Abstract :Research purposes : With the development of high - speed railway in China， the high - speed railway construction planning is renewing，which makes it necessary to insert turnouts into ballastless track of exsisting high - speed railway. On one side，it needs to ensure the operation of railway; on the other side，the track needs to be removed to insert turnouts. The way to solve the inconsistence is the key technical problem faced by high - speed railway develNpment. Research conclusions :( 1 ) Three technological schemes are proposed， including composite sleeper A polyurethane curing ballast bed，long sleeper buried ballastless track，and composite sleeper A ballastless track bed，which are all meet the relevant technical requirements of inserting turnouts into ballastless track of high - speed railway in operation. (2) It is recommended to use the composite sleeper A ballastless track bed scheme while inserting turnouts into baiastless track of high - speed railway which have been put in operation. (3) Through the practice experience in the newly - built Zhangiajie - Jis!iou - Huai!iua railway connecting to the existing Shanghai - Kunming high - speed railway，it has been proved that tiie research achievement can be applied in the track structure design of high - speed railway.
