摘要
针对国内城市轨道交通系统采用直线电机技术却无相应设计规范及标准这一情况,对其轨道系统的主要特点进行分析;采用理论计算和工程类比的方法,对钢轨动态下沉控制值、轨距加宽、轨底坡、曲线超高、扣件支承间距等轨道主要技术标准进行研究和探讨。
The Linear Induction Motor （LIM） has been utilized in domestic urban rail transit system. However, there is no corresponding codes or standards for its design. Making use of theoretical calculation method and engineering analogy method, this paper analyzes major track features of this system, discusses important technical standards for tracks, including control value of dynamic vertical displacement of rail, gauge widening, rail base slope, curve superelevation, and bearing spacing of fastenings, etc.
