　　针对珠三角城际轨道交通主要技术标准及线路特点，提出了适用于城际轨道交通的曲线超高设计技术条件。结合在建穗莞深、佛肇、莞惠三条城际轨道的运行速度和距离曲线，对三条线路无砟轨道曲线超高进行设计研究。计算结果表明：三条线路的欠超高、过超高、欠超高与过超高之和以及超高时变率等限制条件均满足要求，有利于内外两股钢轨均匀受力及钢轨磨耗均等，满足旅客舒适性要求。超高设置是合理的，可为其它城际轨道线的曲线超高设置提供借鉴。

The paper,based on the technical standards and the features of the intercity railway lines in Pearl River Delta,proposes the technical conditions for the designing of the curve superelevation accordingly. The V-S curves of three intercity lines that are currently under construction,namely Guangzhou-Dongguan-Shenzhen,Foshan-Zhaoqing, and Dongguan-Huizhou were used to study and calculate the curve superelevation of the ballastless tracks. The result indicates that the superelevation deficiency,superelevation excess,the sum of the two,and the change rate of superelevation time all meet the requirement. In other words,the force distribution between inner rail and outer rail is more likely to be uniform,while the riding comfort can be guaranteed. Therefore,the superelevation setting is reasonable,and it sets a good example for the projects henceforth.
