| Abstract: | Summarizing the literatures available and analyzing in situ experimental data, and based on the principle of interaction between beam and rail and the compatibility of deformation and boundary, the paper puts forward a new model for calculating longitudinal forces due to temperature variation in gapless track on continuous beam bridge in urban rail transit. The model helps to obtain the longitudinal forces which cannot be acquired by using invariable resistance. A program compiled by C language is adopted for calculation. |
