摘　　要： 依据既有车辆荷载概率模型,通过蒙特卡罗方法将车辆随机过程转化为由车重、车长、车间距等多个参数描述的随机变量,并以此模拟分析车辆荷载效应,然后考虑亚健康梁桥可靠性特点,得出了亚健康梁桥运营车辆荷载限值. According to the existing vehicular load probability models,and based on the Monte-Carlo method,the vehicle random process was converted into many random variable parameters,such as the gross vehicle weight,vehicle length,vehicle space length etc.,then the load effect was simulated.Furthermore,a subsequent study in reference to the structural reliability features of the sub-healthy beam bridge,the vehicular load limit was obtained in this paper.
