重载轨道的设计由于在重载货运铁路中使用大马力机车和更有效的牵引力控制系统，导致轨道质量急剧恶化。这种现象对传统的轨道设计理论提出了挑战。良从采用焊接长钢轨以来，轨道设计者必须保证钢轨牢固就位以抵抗温度力；．还要考虑列车重量和操纵特点引起的垂直力和横向... Design of Heavy Orbit Due to the use of high-powered locomotives and more efficient traction control systems in heavy-haul freight trains, the quality of the tracks is rapidly deteriorating. This phenomenon poses a challenge to the traditional orbital design theory. Since adopting long welded rails, the track designer must ensure that the rails are firmly in place to resist temperature forces. But also consider the vertical weight and horizontal ...
