公路桥梁超限车辆通行安全评价软件的开发

Development of Safety Evaluation Software for Road Bridge Bearing Extra Heavy Vehicle Load

通过挖掘桥梁构造上的承载潜力、材料上的强度储备 ,以及对桥梁承载力进行折减或提高 ,综合确定桥梁承载力 .考虑超限车辆的通行方式和特点 ,更科学、更准确地评定桥梁在超限车辆荷载下的安全状况 .使用MicrosoftVB6 0编程语言开发了大型桌面应用程序《公路桥梁超限车辆通行安全评价系统》Brisafety4 0 .介绍了该软件的设计及组成模块 ,总结了软件开发过程中几个关键问题的解决方法 .软件使整个评价过程完全程序化 .自动化 ,并能给出详细数据、图形结果及具体加固处理方案 .

Through excavating the potential bearing capability of bridge on the structure and the strength store of the material , the bearing capacity of bridge was presented. The safety quality of bridge bearing the extra heavy vehicle was able to be evaluated more correctly in the light of the style and specialty of extra heavy vehicle passing the bridge. The author developed the desk application program 'The Systematic Evaluation of the Safety Quality of Extra Heavy Vehicle Passing the Road Bridge'called Brisafety4 0. It makes the evaluation operate routinely and automatically, and provides the data or graphs and the plan for firming the bridge. The design and modules that composed the program were introduced and several solutions to the key problems in the development of software were summarized.
