摘　　要：对某国道上通行的车辆载荷进行调查 ,并应用随机过程理论对所收集到的车辆载荷数据进行统计分析 ,得到其统计特性 ;然后 ,采用非高斯过程的数值模拟方法对上述车辆载荷实行再现 ,并通过MTS试验系统实现随机载荷下碳纤维薄板 (Carbonfibersheet,CFS)增强钢筋混凝土梁的疲劳试验。试验结果表明 。The research is based on random process theory to analyze the vehicles load data of vehicles collected in National Road, and get its statistic character, then use the non-Gaussian data simulation process to represent those vehicles load mentioned before. Finally, with the use of MTS testing system, the fatigue test of reinforced concrete(RC) beams strengthened with Carbon fiber sheet (CFS) is realized under the random load. The test result proves that the random load fatigue testing method works very well.
