【摘要】：近年来桥梁施工事故时有发生，桥梁施工过程的安全隐患备受关注。怎样提前预测危险因素，避免事故的发生，是摆在桥梁建设者面前的一个难题。本文以斜拉桥为研究对象，对斜拉桥施工过程的安全预警理论及智能预警技术展开研究。主要研究成果如下：（1）详细统计分析了最近二十多年来发生的典型桥梁事故，，总结桥梁事故的特点及发生的原因；分析经典的事故致因理论，将桥梁施工事故的原因归纳为人、物、环境、管理四个方面；通过几例经典的斜拉桥施工事故，提出了减少桥梁施工事故的对策。（2）建立斜拉桥施工过程智能安全预警理论，提出了预警系统的任务目标、系统的功能和组成内容；形成预警系统的工作流程；构建了预警指标体系，包括预警指标体系构建的原则、预警指标的筛选方法、数据处理的方法、斜拉桥施工过程安全预警的准则以及报警的方法。（3）基于MicrosoftVisualStudio开发平台，运用MicrosoftSQLServer数据库和C#语言开发了斜拉桥施工过程安全预警软件。该软件实现了监测数据的规范管理、数据分析直观化及智能安全预警。（4）以如皋长江大桥为背景，将斜拉桥施工过程智能安全预警系统成功应用于实际工程。
[Abstract]:In recent years, bridge construction accidents occur from time to time. How to predict risk factors in advance and avoid accidents is a difficult problem for bridge builders. Taking cable-stayed bridge as the research object, this paper studies the theory of safety early warning and intelligent early-warning technology of cable-stayed bridge construction process. The main research results are as follows: (1) the typical bridge accidents in recent twenty years are analyzed in detail, the characteristics and causes of bridge accidents are summarized, and the classical accident cause theory is analyzed. The causes of bridge construction accidents are summarized into four aspects: human, material, environment and management, and through several classic cable-stayed bridge construction accidents, The countermeasures to reduce the bridge construction accidents are put forward. (2) the intelligent early warning theory of the construction process of cable-stayed bridge is established, the task goal, the function and the content of the early warning system are put forward, and the work flow of the early warning system is formed. The early warning index system is constructed, including the principle of constructing early warning index system, the screening method of early warning index, the method of data processing, the principle of safety early warning in construction process of cable-stayed bridge and the method of warning. (3) based on Microsoft Visual Studio development platform, Using Microsoft SQL Server database and C # language, the construction process safety warning software of cable-stayed bridge is developed. The software realizes the standardized management of monitoring data, the visualization of data analysis and intelligent security warning. (4) taking Rugao Yangtze River Bridge as the background, the intelligent security early warning system of cable-stayed bridge construction process is successfully applied to practical engineering.
