Standard vehicle design load model design method for bridge under special traffic load
The invention discloses a standard vehicle design load model design method for a bridge under a special traffic load. The method comprises the following steps: 1, collecting traffic composition and vehicle parameter information of a special traffic load area; 2, carrying out mathematical statistical analysis on the collected parameters to obtain statistical values or probability distribution functions of the corresponding parameters; 3, compiling a special traffic load motorcade generation program according to the analysis result, and calculating the effect generated by the control section when the motorcade passes through a plurality of bridges with different spans; 4, analyzing the effect value to obtain a probability distribution parameter of the effect, and further calculating to obtain a control cross section effect standard value meeting bridges with different spans and different service lives; 5, according to the result of the previous step and the effect equivalence principle, calculating a standard automobile design load model parameter look-up table meeting bridges with different spans and different service lives; according to the invention, guidance can be provided for bridge design with special traffic loads, so that a bridge automobile design load model bearing the special loads is more targeted, and the problems of economic waste or potential safety hazards caused by over-conservative or insufficient safety reserve in bridge design and construction are avoided.
一种特殊交通荷载下桥梁的标准车辆设计荷载模型设计方法，包括：一，对特殊交通荷载区域的交通构成及车辆参数信息进行采集；二，对采集到的参数进行数理统计分析，得到相应参数的统计值或概率分布函数；三，根据上述分析结果编制特殊交通荷载车队生成程序，并计算车队通过若干不同跨径桥梁时控制截面产生的效应；四，对效应值进行分析，得到效应的概率分布参数，进而计算得到满足不同跨径、不同运营年限桥梁的控制截面效应标准值；五，根据上一步结果及效应等效原理算出满足不同跨径、不同运营年限桥梁的标准汽车设计荷载模型参数查询表；本发明能够为特殊交通荷载的桥梁设计提供指导，使得承受特殊荷载的桥梁汽车设计荷载模型更具有针对性，避免桥梁设计建造中安全储备过于保守或不足导致经济浪费或形成安全隐患问题。
