摘    要:针对车辆荷载与速度在路面结构破坏中的重要性,通过现场试验,对新建高速公路在不同载重及不同速度的车辆通过条件下路面的动态响应(动应变、动应力)规律进行了研究.研究表明,应力-应变峰值随载重的增加而增大,而随速度的增加而减小;前轮应力应变峰值随载重增加而增大的幅度总体上要小于后轮;前轮水平横向应变峰值随载重增加而增大的幅度要小于纵向,而后轮的横向应变与纵向应变的增幅比较接近;速度变化引起的应力应变幅值变化不如载重变化引起的显著;随着深度的增加,车辆行驶产生的动应力对路面的影响迅速减弱.

关 键 词:路面结构  载重  速度  应力应变  现场试验

Abstract:In light of the importance of vehicle loads and speed in damage of road pavement structure, dynamic responses of road pavement under different vehicle loads and speeds are researched through in-situ experiments on a newly-built freeway. The research results show that the peak values of stress and strain increase with accretion of vehicle loads; but decreases with speed increasing; the increasing range with loads of the landscape orientation strain of front-wheel drive is less than the vertical strain of fro...
Keywords:road pavement structure  loads  speed  stress and strain  in-situ experiment
