Design And Data Analysis On Dam Safety Monitoring System

Along with the rapid development of the dam engineering and the in-depth exploitation of the hydroelectric resources, the dam safety issues are becoming increasingly prominent. The research work on a dam safety monitoring technology has been launched by scholars and experts of this field. At present, the offline analysis based on C/S mode is given priority to safety monitoring on the small and medium-sized dam in our country, which can't analyze the behavior and operation of the dam in a real-time, a comprehensive way.In view of the above problem, as the concrete dam in a hydropower station to be a research object, dam safety monitoring system based on B/S structure has been built and the collected data are analyzed and summarized, the real-time, on-line, accurate dam safety monitoring is realized. The main study contents and the results can be summarized as follows: Firstly, the current development of the dam safety monitoring system structure and data analysis are summarized, and the inevitable trend of the dam safety monitoring system that the software system based on B/S structure using the Web technology is pointed out. Secondly, the dam safety automation monitoring system based on B/S structure is designed and expounded. This includes the requirement analysis, system development mode, system framework, system main function, the security of the system safeguard etc. Thirdly, as the concrete dam for a monitoring object, the mathematical statistical model of the dam predictand of deformation displacement is summarized, detailed introduces the modeling theory of multivariate linear regression and its effect analysis, the idea of stepwise regressive model and the specific steps of arithmetic realization, the algorithm theory of partial least-squares regression and the theory of RBF neural network. Fourthly, taking the concrete dam of the hydropower station as an example, the data are analyzed using the monitoring system designed. The experimental results show that in the three kinds of statistics regression modeling analysis method which are application to analyze the dam, the partial least-squares regression model is the optimal choice.
