Abstract：Pre-stressed concreted simple-supported beam pre-casting with 24 m pre-tensioned broken-line reinforcement is a new type structure which is first adopted at home and one of the new technologies adopted on Qinghai-Tibet Railway，with high technical level,new construction technique and great construction difficulties. Based on its technological features and construction requirement, the techniques for pre-stressed concrete and the control value of durable concrete construction are well worth spreading to use and studying.
