Abstract： Jintai railway is a single track electrified railway with a speed of 160km / h. ballastless track is laid within the tunnel with a length of more than 6km. The elastic support block ballastless track has the characteristics of low noise and high smoothness. According to its application in the construction site of Jintai railway， it is studied， and the key points of construction technology are summarized from three aspects： construction preparation， construction process and quality control.

Keywords： elastically supported block ballastless track; construction technology; the quality control
