The Effects of Train Braking and Ballast Resistance on the Longitudinal Force in Rail

列车制动与道床阻力对钢轨纵向力的影响分析

By many years experiences, controlling ballast resistance and excessive compressive temperature force of the rail is recognized as the only means to overcome the track buckling.

多年来认为控制道床阻力及钢轨内的温度力是防止胀轨跑道的主要办法。

But in fact, due to the great variation of ballast resistance during track work and change of "stress free temperature" of the rail, they are hard to measure then hard to control.

但道床阻力在作业时变化很大，钢轨在线路上长期使用，锁定轨温可能发生变化，温度力亦不易控制。
