简支梁桥技术状况评定程序研发与应用

Research and Application of Technical Condition Assessment Procedure for Simply Supported Beam Bridge

基于公路桥梁中简支梁桥技术状况评定相关内容、评定指标与方法,借助Matlab环境GUI界面设计、微软组件(COM)对象模型,研制开发了“简支梁桥技术状况评定程序”。用户可根据桥梁现场检测信息,在可视化操作应用界面内输入桥梁基本信息、各项评定指标的定量或定性判定标度信息,程序自动分析检算构件、部件、部位及桥梁总体技术状况评分,判定桥梁技术状况等级分类,生成技术状况评定报告。最后依据苏州市狮山街道塔园路落星桥的2021年技术状况检测评定相关内容,对程序准确性进行验证。

Based on the related contents, evaluation indexes and methods of the technical condition evaluation of simply supported girder bridges in highway bridges, the “technical condition evaluation program of simply supported girder bridges” is developed with the help of matlab environment GUI interface design and microsoft COM object model.Users can according to the detection of bridge site information, application in visual operation interface in bridge basic information input, the evaluation indicators of quantitative or qualitative judgement scale information, automatic analysis program is checked, components, parts of components and the overall bridge technology status, decides the grade of bridge technical condition classification, generate technical condition evaluation report.Finally, the accuracy of the program is verified according to the 2021 technical status detection and assessment of Luoxing Bridge, Tayuan Road, Shishan Street, Suzhou City.
