摘要
分析了路面工况对车路动态响应的影响,研究了不同车速对路面动态响应的影响,讨论了不同质量的车辆对路面的动载作用情况.结果表明:在竖向上随着深度的增加动应力呈衰减趋势;车—路耦合产生的动载作用受路面工况的影响较大,路面等级越低(路况越差),车辆对路面的动载荷越大;车速增加,车辆对路面的动载荷也随着增大;在相同条件下,重型车辆较轻型车辆对路面的动载荷要大很多,即重车对路面的破坏作用更为严重.
The effect of dynamic loads under different pavement conditions was analyzed;the effect of dynamic loads at different speeds was studied;the effect of dynamic loads of different weight of vehicle on the pavement was discussed.The result shows that dynamic stress decreases with the increase of pavement;the effect of road roughness on the dynamic load is obvious and the dynamic load increases significantly with the reduce of the levels of road roughness;the dynamic load increases with the velocity improvement;the dynamic load of heavy truck is much greater than that of small vehicle with the same conditions.
