| Abstract: | 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. |
