根据京珠高速车辆荷载现状的统计数据,构建了2个正态分布和1个极值Ⅰ型分布加权和的三峰概率分布模型,通过和常用概率模型比较分析后,证明此概率分布模型能够有效地反映车辆荷载实测数据概率统计特征。此外,文章研究了六轴重车各轴占总重的比例,采用最小二乘法回归分析了各轴重的参数,并在此基础上,计算了30 m跨径简支梁的荷载效应,为我国公路桥梁车辆荷载标准的研究修订以及车辆荷载分析提供参考。

According to the current data of Beijing-Zhuhai high-speed vehicle load , the three peak probability distribution model of two normal distribution and an extreme value weighted I type distribution was constructed with using the statistics and data fitting method , and this probability distribution model could effectively reflect the characteristics of the measured data of the vehicle load which had been proved after the comparative analysis with the common probability models.So, it has a certain reference value to the vehicle load's analysis.Moreo-ver,the thesis studied each axle load car accounted for the proportion of six axle load car , and analyzed the pa-rameters of each axle load with the least squares regression method .On the basis of this , we calculated the load effect of simply supported beam with 30 m span which could provide the reference to the research of our country highway bridge vehicle load standard and analyze the vehicle load .
