摘要:
在对现有轴裁模型分析的基础上,采用更明确表述车辆荷栽力学效应和交通特征的轴栽应用系数,以高等级公路实测货车轴栽数据为样本.用数理统计方法建立了正常交通道路和重栽交通道路运输车辆的轴载模型.结果表明,无论是正常还是重栽交通,车辆轴栽都服从正态分布,除单轴单轮之外.其他3种轴型的空载和有载也服从正态分布.笔者所建立的模型,避开车型干扰,降低交通调查的难度,弱化模型应用的制约因素,便于工程应用.
Abstract:
In order to ensure the wind safety of the Saiwu Diegor Bridge, which has an extremely important position, the basic wind speed data of the Fuyun County Meteorological Station in the bridge site area were used to analyze the basic characteristics of the average wind speed, maximum wind speed, extreme wind speed over the years, and the average wind speed and wind direction of each month. The maximum wind speed sequence of the weather station was established year by year, and the design basic wind speed at different recurrence periods of the bridge was calculated by using extreme value I. type, Pearson type III. and different specifications. At the same time, considering the different types of land surface in the Karasuk Reservoir where the bridge is located, the design benchmark wind speed at the bridge deck is deduced, which provides an accurate basis for wind tunnel test and wind load calculation during flutter, jitter analysis and structural analysis of the bridge.
