摘要
基于系统工程的预警原理,结合土石坝工程的特点,研究了土石坝工程安全预警系统架构,并将其分为警源分析子系统、警兆辨识子系统、警情分析子系统.重点研究了警源分析子系统和警情分析子系统,并将其中涉及的水库大坝的虚拟现实技术、溃坝洪水估算、下游洪水演进预测等关键技术应用于浙闽台流域某土石坝工程中.结果表明,土石坝工程安全预警系统对预警土石坝的安全具有一定的作用.
Based on the early warning principles of system engineering, combined with the characteristics of an earth-rock dam project, an earth-rock dam safety early-warning system architecture is studied. The system is divided into three subsystems： the warning source analysis, the warning sign identification and the warning situation analysis. The warning situation analysis subsystem involves some key technologies, such as virtual reality, dam-break flood estimation and downstream flood evolution forecasting. The application of these key technologies to an earth-rock dam project shows that the earth-rock dam safety early-warning system provides an important early-warning reference value for earth-rock dam safety.
