轨道位置的持久性取决于道床的稳定性。迄今为止所采用的密实道碴的方法都没有能使道床的稳定性达到最佳状态。今天,一种新型机械——动力稳定车——能从空间方面密实道碴,以此获得所需之稳定性,达到预期效果。 铁路管理部门一再提出要有一种机械使轨道位置能保持较长时间,曾经设想改变捣固参
The durability of the track location depends on the stability of the ballast bed. The methods used so far for compact ballast have not been able to achieve the best ballast bed stability. Today, a new type of mechanical-power-stabilizing car-can be compactly spatially directed to achieve the required stability and achieve the desired results. The railroad administration repeatedly proposed that there should be a mechanism that keeps the track position for a long time. It has been envisaged to change the tamping parameters
