| 摘 要： | 在平曲线上设置超高,其目的是形成向心力,以平衡车辆在弯道上行驶的离心力.随着公路设计新理念的推广,应结合运行速度理论对不同等级、不同地区、不同交通获况的道路进行更加合理的超高设计,以保证道路行车安全.

| Abstract: | The purpose of setting superelevation on horizontal curve is to form centripetal force in order to balance the centrifugal force of the vehicle traveling on the bend of road. Along with the promotion of new high way design concept, the superelevation design for highways with different levels and traffic conditions in different areas is conducted according to speed theory. It can ensure road traffic safety. |
