高等级公路建设期风险状态预警系统研究

摘要

Associated with the actual situation of high-grade road construction,the paper given out the risk early warning indicators' quantitative methods of the risk early warning system associated with risk analysis theory firstly; then based on the Time Series Analysis,the calculation methods of early warning condition and early warning loss are discussed; lastly,with Matlab language and its graphical user interface (GUI),compiling the dependent program and establishing an risk state analysis system based on the field monitoring data.%结合高等级公路建设的实际情况,首先,利用风险分析理论,给出了风险预警体系中相关指标的定量计算方法;然后,采用时间序列分析方法,对预警条件和预警损失的评价的方法进行论述,给出了预警条件评价公式;最后,借助Matlab语言及其图形用户界面(GUI),编写相关程序,建立了基于现场监测数据的风险状态预警信息分析系统,实现了预警过程的可视化操作.
