| Abstract: | Basing on interrelated action principium of beam and rail, we build a mechanics model and use finite dement method to calculate and analyze the principle of discrete force of welded railway on special designed simple supported bridges. The result can give some advice to the design of continuously wdded rails on bridges, which to ofter a reference for rdevant technical staft. |
