摘要
叙述在美国明尼苏达州Mn/ROAD研究设施进行的刚性路面动力反应试验研究工作。试验中选择了三个刚性路面研究断面,通过采集两种重量的卡车以不同速度通过时,刚性路面板不同位置和不同深度部位处动应变计、缩缝传力杆钢筋应变计的应变时域变化曲线和路基顶面动土压力计的土压力时域变化曲线,获得了刚性路面板顶面和底面的纵向和横向动应变特征、缩缝传力杆动应变特征和路基顶面动土压力特征以及影响刚性路面板动应变特征的参数等的测试数据,为进行理论分析提供了重要基础。
An experimental study on rigid pavement dynamic response is conducted in the Mn/ROAD facility located in Minnesota of the United States. The data on the longitudinal and traverse dynamic strains at the upper and the bottom of the slab, the dynamic strain in dowel bar, and the dynamic soil pressure at the upper subgrade are obtained, through choosing three sections and collecting the time-dependent curves of the dynamic strains in the rigid pavement slab and the soil pressure at the upper subgrade, when the Mn/ROAD truck with two kinds of weights is passing at different speeds.
