研究目的：结合工作实践、工作需要，针对曲线超高的力学作用，系统分析对铁路技术条件的关键影响。以便在铁路线路设计中具有参考价值和必要的指导作用。
研究结论:曲线超高是线路平面、纵断面设计和轨道设计的重要技术条件。( 1) 影响曲线半径、速度目标值等主要技术标准的选择; ( 2) 影响着通过曲线的允许最高、最低速度，缓和曲线长度，铁路限界和轨道选型等技术条件的规定; ( 3) 影响着铁路运输安全、旅客舒适度、运营养护成本等运输安全经济指标。
Research purposes: In combination with the working practice and demand， the systematical analysis of the mechanic effect of the curve super － elevation on the railway technical condition is made for the purpose of providing the reference and guidance to the design of the railway track．
Research conclusions: The curve super － elevation is one of important technical conditions for the track plane design，the track vertical section design and the track design． ( 1) The curve super － elevation can influence the choice of the technical standards，such as the curve radius and the speed target value． ( 2) The curve super － elevation can influence the stipulating the technical conditions，such as the maximum and minimum speeds of the curved track，the length of the transition curve，the railway clearance and the model selection of the track． ( 3 ) The curve super － elevation can influence the railway traffic safe and economic indexes，such as the railway traffic safety，the passenger comfortableness and the operational and maintenance costs．
