摘要
采用平衡更新过程、蒙特卡洛方法和《公路桥梁承载能力检测评定规程》等3种方法对实际车辆运营状态下一座连续梁桥的车辆荷载效应进行分析和比较,为车辆荷载效应分析方法的选择提供依据。结果表明,平衡更新过程、蒙特卡洛方法两种方法得到的结果最大相差5%,《公路桥梁承载能力检测评定规程》的计算活载增大系数偏小。因为蒙特卡洛方法理论和计算过程更为简洁,在基于动态称重(Wight-in-motion)系统的车辆荷载效应计算中可以优先使用。
In order to provide baseline for selection of vehicle load effect analysis method, the Equilibrium Renewal Stochastic Process Theory, the Monte Carlo Simulation method, as well as 《Specification for Inspection and Evaluation of Load - bearing Capacity of Highway Bridges》 were applied to analyze and compare the vehicle load effect of girder bridges in actual running state. Results show that the errors between the results from the Equilibrium Renewal Stochastic Process Theory and the Monte Carlo Simulation method is within 5%, live load amplified factor based on 《Specification for Inspection and Evaluation of Load - bearing Capacity of Highway Bridges》is obviously small. Because the simple theory and calculation process, the Monte Carlo Simulation method will be recommentd priority.
