论文摘要
道路波纹是指未铺设的道路表面上周期性的,横向波纹的形成。它在交通繁忙的情况下自发形成在最初的平坦表面上,被认为是一种不稳定的生长现象,可能是由于移动车辆的重量而导致的,可能是由于底层土壤的局部体积收缩而引起的。在目前的工作中,我们使用土壤巩固和数值模拟的实验数据证明了道路波纹的可能机制。结果表明,由于表面的初始不规则性而激发了移动车辆的垂直振荡,在波纹的发展中起着关键作用。
Road corrugation refers to the formation of periodic, transverse ripples on unpaved road surfaces. It forms spontaneously on an initially flat surface under heavy traffic and can be considered to be a type of unstable growth phenomenon, possibly caused by the local volume contraction of the underlying soil due to a moving vehicle's weight. In the present work, we demonstrate a possible mechanism for road corrugation using experimental data of soil consolidation and numerical simulations. The results indicate that the vertical oscillation of moving vehicles, which is excited by the initial irregularities of the surface, plays a key role in the development of corrugation.
