摘要
为了对公路桥梁结构在交通荷载作用下的极限效应进行分析,结合上海市浙江路桥及其近郊交通荷载的调查统计与估测结果,利用蒙特卡洛方法对交通荷载进行了随机模拟,之后通过莱斯理论外推出各构件对应于50年重现期的车辆荷载作用极限值。主要对公路桥梁随机车辆荷载的模拟和车辆荷载作用极限值推算进行了系统的理论介绍,并基于实桥调查给出具体的方法应用,为交通荷载安全评估提供基础。
To analyze limit of highway bridge structure under traffic load effect, Monte-Carlo stochastic simulation method was applied in the simulation of traffic load, and then through the theory of Rice deduced the vehicle load limit for 50 years return period of each component based on traffic load investigation statistics and evaluation of Zhejiang road bridge in Shanghai, and its suburb in this paper. This paper mainly systematically introduced the theory of highway bridges random vehicle load simulation and vehicle load limit calculation, and presented the application method based on actual bridge survey, providing a basis for traffic load safety assessment.
