|
摘要
车辆荷载是桥梁设计的一个重要技术指标,不同设计基准期内的车辆荷载效应极值是对桥梁进行可靠性评估、疲劳寿命评估等的重要基础。结合国内外研究现状,介绍了获取桥梁车辆荷载效应的方法及基本理论,包括采用仪器读取车辆荷载效应和基于不同数据来源的车辆荷载模型获取荷载效应,并指出了各种方法的优点及适用性;还简述了对车辆荷载效应进行极值外推的方法,提出了各种方法的优点及其局限性,研究表明,荷载效应的尾部数据对极值外推结果的精确性有显著影响。
Vehicle load is an important technical index of bridge design,and the extreme value of vehicle load effect in different design reference period is the important foundation for reliability evaluation and fatigue life evaluation of bridge. Combined with the research status at home and abroad,the methods and basic theories for obtaining the load effect of bridge vehicles are introduced,including reading the load effect of vehicles by instruments and obtaining the load effect of vehicles based on vehicle load models of different data sources,and the advantages and applicability of various methods are pointed out. The methods for extreme extrapolation of vehicle load effect are also introduced,and the advantages and limitations of various methods are proposed. The results show that,the tail data of load effect has significant influence on the accuracy of extreme extrapolation results.
