按重载交通设计的桥梁承载能力研究

Analysis on Load Carrying Capacity of Bridge as Heavy Truck Traffic Designed

根据宣大高速公路的重载交通特性,对其车辆进行秤重分类,按照测量统计的车辆纵向排列图示,对该路各种桥梁结构进行受力分析及强度检算,根据检算的结果,在考虑了桥梁的安全,又考虑了宣大高速公路的具体情况,对于按重载交通设计的宣大高速公路,为了提高运营效益,尽快回收建设资金,提出了重载交通高速公路的限载标准.

According to the characteristics of heavy truck traffic of the Xuanhua-Datong Expressway, it is weighted and classified that the vehicle moving on the Expressway. The mechanics analysis and strength checking of the various bridge structures of the Expressway are made, based on the statistical arranging diagram in a line of vehicles that measured, as the result of analysis, considering the safety of bridges and the specific situation of Xuanhua-Datong Expressway, it is put forward that the load limiting standard of the expressway of heavy-duty traffic, in order to increase the running economic results and get back the construction fund as quickly as possible.
