摘　　要：曲线路段往往是事故多发路段,尤其是重型载重车辆的超载快速行驶更易引发侧翻倾覆的重大交通事故。该文探讨道路因素和车辆因素对曲线路段行车安全的影响,提出满足车辆横向稳定性的最大容许车速,并利用此方法量化超载车辆的安全限速指标,为提高曲线路段行车安全提供参考。The curved road sections are the sections where the accidents happen sometimes,especially the overloading high-speed driving of the heavy loading vehicles is easy to cause the major traffic accidents of side-turning and overturning.The article approaches the influence of the road factor and the vehicle factor on the driving safety in the curved road sections,put forwards the maximum per-mitted driving speed to meet the transverse stabilization of the vehicles,and utilizes this method to quantize the safe limit speed index of the overloading vehicles able to provide the reference for en-hancing the driving safety in the curved road sections.

关 键 词：极限最小半径 超高 设计车速 超载
