摘要
阐述曲线外侧路堤边坡沿路肩失稳 ,以及沿道心和路肩一侧滑坡的现象 ,分析列车作匀速曲线运动产生的横向力 ,包括未被平衡离心力、导向力的作用 ,以及地表水、地下水对路基稳定性的影响 ,列举一例做抗滑稳定性检算 .
External lateral decent curved fills is proposed to be checked by balance objects.The transverse form produced by the train making uniform rectilinear curve movement is analyzed, with an account of unbalanced power, track power, and the influence of surface water and nudergrounder water on the stability of roadbeds and their countermeasures. An example is given to show how to counter the external lateral decent.
