摘要
为解决斜拉桥施工监控过程中测量数据量庞大、管理和分析任务繁重而易出错的技术难题,基于数据库技术、水晶报表技术和Visual Studio 2008编程环境,开发了斜拉桥施工监控数据处理系统。该系统从斜拉桥施工监控的基本理论入手,实现了监控过程中施工误差识别和利用识别结果进行补偿修正有限元模型的问题,解决了利用关系型数据库快速、智能地形成各种报表的关键问题。该系统成功应用于武汉二七长江大桥的施工监控,使现场监控工程师可以专注于结构分析,而非数据处理。
To cope with the technical problems that the amount of measurement data in the construction monitoring and control of cable-stayed bridges is great, the work load of the data management and analysis is heavy and the errors are liable to occur, a data processing and man- agement system for the construction monitoring and control of the bridges has been developed on the basis of the data base technique, crystal report technique and Visual Studio 2008 program- ming environment. Proceeding from the fundamental theory of the construction monitoring and control of the cable-stayed bridges, the system achieves the purpose of identifying the construc- tion errors in the process of the construction monitoring and control, compensating and updating the finite element models, using the results of the identification and also solving the critical prob- lem of fast and intelligently forming various reports, using the relationship type data base. The system has already been successfully applied to the construction monitoring and control of Wuhan Erqi Changjiang River Bridge and therefore enables the site monitoring and control engineers of the bridge to devote themselves to the structural analysis rather than the data processing.
