| Abstract: | Based on the analysis of the lateral acceleration data of vehicles measured in Shanghai Metro Line3,this paper suggests that the lateral oscillation force of the vehicles shall choose 10% of the vertical load on a single wheel.Since the lateral offset of the derailed vehicles may reach 1.75 m on both sides of the rail,it is recommended that the strength of the bridge plates and stability of the whole structures of the single-line bridges (including piers) be tested in the incidentally loaded status of the bridges. |
