| Abstract: | For the passenger dedicated railway line with speed target 300 km/h,the 32-m span simply-supported box girders are the major girders that will be used for small span bridges and the utilization of precasting and erection construction method will be the best choice of guaranteeing both construction quality and construction time limit.In this paper,the key technology for precasting of the 32-m span simply-supported double-track box girders is dealt with. |
