摘要
无碴轨道是一种新型的轨道结构型式,越来越多地应用于高速铁路。目前,无碴轨道结构计算理论还不完善,多采用叠合梁的方法。现采用平面有限元方法,把荷载和轨道结构看成一个系统,对板式无碴轨道在荷载作用下的竖向位移和内力进行了分析,并通过MATLAB编程实现,计算结果符合无碴轨道结构基本原理。
The ballastless track is a new kind of track structures and is applied in high-speed railway more and more widely. So far, the calculation theory of ballastless track structures is not fully built, and the method of composite beam is commonly used its calculation. In this paper, the author regards loads and track structures as a system and analyzes the vertical displacement and internal force of slab ballastless track structures under the loads by plane finite element method. The results are obtained by MATLAB programs, and conform to the basic principle of ballastless track structures.
