Safty Monitoring Model of Concrete Dam Based on Identification of Dynamic Attribute Interval

Based on correlation analysis in displacement of concrete dam and its influencing factors,considering the complex nonlinear properties in the process of evolution of concrete dam,and integrated applying phase space reconstruction,dynamic structure mutational theory and other numerical analysis methods,effectively identified the mutational position.In response to the relative stability dynamic structure,this paper studies the realization method and principle of the safty monitoring model to concrete dam for long-term service.Through a concrete arch dam instance indicates that the fitting and prediction precision of the concrete dam displacement monitoring model can be effectively improved.
