本文首先对京沪高速铁路各个时期所能实现的最高速度进行了论证，并据此推算出最小曲线半径值；根据大站前后各个路段可能实现的行车速度，拟定了其相应的曲线半径标准；最后对国曲线的最小长度、缓和曲线长度，最小转向角与曲线地段线距加宽等曲线设置问题，提出了商榷意见． In this paper, the maximum speeds that can be achieved in various periods of the Beijing-Shanghai high-speed railway are first demonstrated, and the minimum curve radius values ​​are deduced therefrom. Corresponding curve radius standards are formulated according to the probable speed of each section before and after the stations. Finally, the author puts forward some suggestions on the setting of curves such as the minimum length of national curve, the length of mild curve, the minimum steering angle, and the widening of line spacing between curves.
