Mechanical Characteristics of Concrete Ballastless Track on the Track Traffic of Linear Induction Motor

摘要

In this paper, based on the elastic foundation beam theory, the influence rules of every combination of loads and operating modes for ballastless track of Linear Induction Motor (LIM) track traffic are studied. In addition, according to the construction character of prefabrication and cast-in-situ, the rules of how construction influences the mechanical characteristics of the ballastless track structure are given. On the basis of synthetical analysis of the distribution rules of ballastless track's internal force, some appropriate suggestions for design and construction are put forward.
