摘　　要：本文对典型小半径曲线进行了长期观测,分析外股钢轨侧面磨耗的发展规律。通过对实际超高值调整进行超高改造,分析改造后的磨耗发展规律,得出合理调整后的超高。设置一定的欠超高,有利于减缓外股钢轨侧磨,延长钢轨使用寿命及换轨周期,对后续小半径曲线磨耗整治工作具有一定的指导意义。This paper analyzes the development laws of outer rail side wear through long-term observation of typical small radius curves. The superelevation improvement,conducted by adjusting the actual superelevation values,can help to analyze the laws of rail wear development,thus obtaining reasonably adjusted super elevations. Setting certain deficient super elevations is conducive to mitigating the outer rail side wear so as to prolong rail service life and rail renewal period,which will have certain guiding significance for subsequent tasks of small radius curve wear rectification.
