轻轨线路采用正常线间距单渡线的研究

A Research on the Single Crossover Adopted on LRT Line

分析了正常线间距单渡线在中国未被采用的原因 ,依据列车通过单渡线夹直线时稳定性及乘客舒适性条件 ,举例说明了采用正常线间距单渡线是能够满足行车稳定性和乘客舒适性条件的。提出了正常间距单渡线实施过程中需要采取的具体措施 ,包括其夹直线处短轨及其绝缘接头的处理问题。

The single crossover of ordinary midway between tracks is not yet adopted in China.This paper gives examples to explain that the single crossover of ordinary midway between tracks could meet the requirements of the operational stability and the comfort for passengers,when trains pass through intermediate straight line on single crossover.The problem is,as the author argues,how to take the detailed measures in engineering process,including the technique to deal with the short rail and the insulated joint in the single crossover of ordinary midway between tracks.
