Research on Design Method of Bearing Platform of Arch Bridge on Railway Passenger Dedicated Line

At present,there is no definite railway standard that can be relied upon for the design of bearing platform of arch bridge of railway passenger dedicated line.To solve this problem,the paper,by establishing the interaction model among piles,soils and bearing platforms,illustrates how to calculate the stresses and reinforcing bars of the bearing platform with above-mentioned interaction model under the action of upper structure.Furthermore,the paper expounds and proves that: the result of reinforcing bars obtained from above-mentioned interaction model is more secure than the result obtained from the existing standard method.This research will be useful for the design of bearing platform of arch bridge in future.
