This thesis carries on working condition simulation experiment of the box girder structure property,and illustrates experimental methods from aspects of bracing mode,loading method,measuring-point arrangement,and experimental procedure and so on.The experimental result shows that the structural property of the box girder meets the utilization demand.%对某高速公路一中桥箱梁的结构性能进行了模拟工况实验,并从支承方式、加载方式、测点布置、试验程序几方面对试验方法进行了说明,试验结果表明：该箱梁的结构性能满足使用要求。
