Research on the Design of Simply Supported T-Beam with Single Track Mix-Gauge for the Suifenhe Railway Bridge Between China and Russia
The Suifenhe Railway adopts single track mix-gauge technology to meet the traffic needs of Chinese and Russian trains.Due to significant differences in the calculation methods for train live loads between China and Russia,this article proposes an equivalent loading diagram for CK live loads by comparing the uniformly distributed load values obtained from the conversion of live loads between the two standards.In response to the spatial stress complexity of the 32 m simply supported T-beam on the Suifenhe Railway curve under the two constant and CK live loads of the curve layout,this paper establishes beam grillage and solid finite element models to deeply analyze and summarize the stress and internal force distribution of the structure in the longitudinal and transverse directions.The lateral distribution coefficients of the inner and outer beams under constant and CK live loads are proposed,which guides the design of this project and provides technical support and reference for similar projects.
