摘要
曲线超高、轨道临界横向抗力、轨距保持强度是控制列车曲线通过速度的主要参数。作者介绍了国外主要铁路在上述参数方面的有关试验资料、计算公式及控制标准，揭示了在这些领域仍有待研究和解决的许多重要课题，并对我国铁路既有线提速过程中上述参数值的选用及相应的曲线通过速度安全评估方法提出了建议。
Curve superelevation,critical transversal track resistance and gauge keeping strength are the principal parameters governing the passing speed of trains over the curve.The paper makes a survey of related experimental results,calculating formulas and control criteria,discovers many important topics thereof that remain to be solved,and then puts forward some proposals regarding the selection and application of these parameters in the process of speed raising on existing railway lines of the Chinese railways as well as the safety evaluation method for train passing speed on curved tracks.
