The Operating State Analysis Of The Concrete Gravity Dam Of MANWAN Hydro Power Plant

Based on the theory of inverse analysis in Mechanics and Engineering and combined with the concrete gravity dam of MANWAN Hydro Power Plant, a back-analysis model including the prior information was built and Artificial Neural Network (ANN), according to which powerful nonlinear mapping ability, was used to predict the future physical parameters of the concrete. Consequencely, the analysis and assessment system of the operating state of the concrete dam was developed under the ANSYS development environment, and the back-analysis and the prediction of the parameters of the dam system have been done according to the operating observed data. The research work involves several aspects as follows:1) a back-analysis model including the prior information and a predictive model of nonlinear time series were established;2) The analysis and assessment system of the operating state of the concrete dam was developed under the ANSYS development environment, in which the analysis module of the loading effects, the back-analysis module, the forecasting module of the physical parameters and the assessment module of the operating state were contained;3) According to the operating observed data, the operating state of the dam was assessed and predicted with the analysis system of the operating state, the results suggested that the dam is in basically normal operation at present.
