摘　　要：随着开行5000t重载列车和旅客列车提速,在京沪线重载快速区段上出现了大量的直线钢轨交替不均匀侧面磨耗,使直线轨道平顺性指标恶化,导致某些机车在运行过程中剧烈摇晃。文中对重载快速区段直线钢轨交替不均匀侧磨的预防与整治作一些探讨。With the operation of 5,000 t heavy-load trains and the speed raising of passenger trains, a large quantity of straight rails with alternative uneven side wearing appear in the heavy-load and fast-speed section of the Beijing-Shanghairailway line, which makes the smooth-going index of straight rails worsen and causes some locomotives vibrate violently during their operation . This article gives some discussion on the prevention and maintenance of the straight rails with alternative uneven side wearing in the heavy-load and fast-speed section.
