| 摘 要： | 为了模拟桥梁所受活载的真实情况,从321国道上某刚架拱桥统计某一时段内通过该桥的车流量,并通过对车流量的等效折算、概率分布及其功率谱密度函数等统计分析,得到这一随机过程的统计特性:服从威布尔分布的非高斯过程。

| Abstract: | Data of classified traffic were acquired from a rigid frame arch bridge on 321 National Highway in a period of time to simulate the process of random loading on bridges. Statistical approaches, such as equivalent conversion, probability distribution, and power spectral density function, were employed for the analysis of the da?ta. Results of the analysis indicate that the random process is a non-Gaussian process obeying Weibull distribution. |
