Abstract:

To investigate the water film depth (WFD) of super-multi-lane (SML) pavement and its effect on tire-pavement surface interaction, a rainfall-runoff model of SML pavement was developed, and the influence of the number of lanes and pavement slopes was analyzed. Based on the realistic texture of pavement surface, a tire-pavement surface-water film coupling model was established. The contact characteristics between the tire and the pavement surface, as well as the critical hydroplaning speeds under different WFDs, were analyzed. The results show that the WFD of the pavement increases significantly with the increase in lane number. Pavement expanding from three to five lanes in a single direction has the largest increase of the WFD, while the increment decreases as the number of lanes further increases. Increasing the transverse slope from 1.5% to 2.0% results in the most obvious decrease in the WFD. Moreover, increasing the longitudinal pavement slope to 1.0%-2.0% significantly reduces the area of thick water film on the pavement surface. The higher WFD results in a more rapid decrease in the tire-pavement surface contact force as the vehicle speed rises, leading to a lower critical hydroplaning speed. The critical hydroplaning speed of the vehicle decreases by approximately 6 km/h for every 2 mm increase in the WFD.

为研究超多车道(SML)路面水膜厚度(WFD)及其对轮胎-路表相互作用的影响,构建了SML路面的降雨汇流模型,分析了车道数和路面坡度对WFD的影响。基于路表真实纹理,建立了轮胎-路表-水膜耦合模型,分析了不同WFD下轮胎与路表接触特征及轮胎临界滑水速度。结果表明,随路表车道数的增多,路表水膜厚度显著增大。当路面从半幅3车道拓宽至5车道时,WFD增加最显著,但其增量随车道数进一步增加而逐渐减小。当路面横坡从1.5%增至2.0%时,WFD降低幅度最大。将路面纵坡增加至1.0% ~ 2.0%,路表较厚水膜的分布面积明显减少。WFD越大,胎-路间接触力随车速增加而下降得越快,导致临界滑水速度越小。WFD每增加2 mm,车辆临界滑水速度下降约6 km/h。
