摘　　要：通过对小半径曲线常见的悬浮、轨道破坏、爬轨 3种脱轨情况的特点分析 ,从工务角度着重论述小半径曲线上的超高顺坡率、轨距超限、方向水平及其反相位复合不平顺三者对行车安全的影响 ,并提出预防整治的对策措施。Based on analysis of three commonly\|seen derail cases over small radius curves, i.e., suspension, track damage and climb on rail, an introduction is given to three key elements concerning safety of train operation, that is the superelevation run\|off elevation, out\|of\|gauge, alignment level and its reverse phase composite unevenness. Countermeasures are put forward.

关 键 词：小半径曲线 脱轨原因 铁路 轮轨关系复合脱轨事故 预防 整治
