摘要

The over-seat single-track transit system has been widely used. At present, the operation technology is well studied. However, the study of the emergency track beam on single-track transit lines is still a blank. The over-seat single-track transit system is firstly introduced in Chongqing city of China. Therefore, it is essential and meaningful to carry out the research about design and study of its emergency track beam. The emergency track beam is a replacement structure of the PC beam. Manufacture experience of the military railway beams and design method of the ordinary steel track beams are adopted in the paper. Assembly theory of the prefabricated sections and modularization design methods are also introduced in this paper. The different sections are assembled into an emergency track bean which can replace the destroyed PC beam with high strength bolts and connection plates. The values of loads on the emergency track beam are analysed in this paper. Then, by using the Finite element program, a model of emergency track beam is established with 100m curve radius and 22m length. The paper discusses the strength and the stiffness of the emergency track beam. And the dynamic behaviour of the structure is analyzed. Last, the natural frequency and modal shape of the emergency track beam are obtained. The above research results provide theory analysis and guidance for the application of emergency track beam. They also provide the conference for the design and study of other assembly structures.
