| Abstract: | Shali River Bridge was built using prestressed hollow core slabs.The dynamic indexes and performances of Shali River Bridge were obtained through the onsite static and moving load experiments.The carrying capacity and technical conditions of this bridge were assessed according to the test results by comparing with the theoretical values,and then the design and construction quality were valued,which provides a scientific basis for the complete acceptance and safe operation. |
