摘要:

在高速公路桥梁结构极限承载力和可靠性研究中,由于规范中没有车辆荷载的统计参数,无法直接进行可靠性分析,因此有必要首先进行荷载统计参数和加载模型的研究.基于英国交通研究实验室于1990年进行的历时2周的统计调查所得的WIM数据,利用Microsoft Visual Basic(6.0版)编制分析程序,首先根据各种不同车辆出现概率统计出5种最常见载重卡车;然后分别统计其构形、轴重、总重及桥跨为变量时多辆卡车在桥梁上同时出现的概率.统计结果可直接用于桥梁结构体系可靠性分析.

Abstract:

In the study of ultimate bearing capacity and reliability of highway bridge structures, since there are no statistical parameters of vehicle load in the specification, reliability analysis cannot be carried out directly, so it is necessary to first study the statistical parameters of load and loading model. Based on the WIM data obtained from a two-week statistical survey conducted by the British Transport Research Laboratory in 1990, the analysis program was compiled using Microsoft Visual Basic (version 2.6), and the five most common trucks were first calculated according to the probability of the occurrence of various vehicles; Then, the probability of multiple trucks appearing on the bridge at the same time when their configuration, axle load, total weight and bridge span are variables. The statistical results can be directly used for the reliability analysis of bridge structural system.
