Abstract

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. Moreover,the thesis studied each axle load car accounted for the proportion of six axle load car, and analyzed the parameters 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.

Key words

vehicle load / three peak distribution / distribution fitting / load effect
