摘要/Abstract

摘要： 由设计初期道路混合交通量、混合交通中的轴载类型与轴重分布等测量参数来预估道路设计期内混合交通等效标准轴载的当量作用次数(ESAL).并根据误差分析及误差传递理论,通过以上统计测量参数误差,对ESAL的总合成误差进行分析计算,以供道路可靠度分析与道路设计使用.

关键词: 混合交通, 等效标准轴载, 误差传递, 合成误差

Abstract: By using the measured parameters, such as initial mixed traffic volume, axleload type, axleload distribution, etc., this paper introduces the method of evaluating the ESAL of mixed traffic during road expectancy life.Also, according to the error analysis and error transfer theory, by using the errors of the statistical measured parameters above, the synthetic error of ESAL is analyzed.The result obtained can be used for analysis of road reliability and road design.

Key words: mixed traffic, equivalent standard axleload, error transfer, synthetic error
