Application of MGM(1,N) on Concrete Temperature Prediction of RCC Dam
The basic modeling principal and method of grey mathematics model is introduced , taking the case of JiangYa RCC gravity dam, on the basis of the interior of dam concrete temperature monitoring data , According to Multi-Variables grey principal, model is founded , change character of concrete temperature is analyzed, and the development tendency of interior concrete temperature is predicted on the basis of the influencing factor-water temperature, air temperature and rock temperature by Multi-Variables grey principal. It is proved that the model founds successfully and it’s goodness-of-fit is very well. calculation base for the temperature stress of dam concrete is provided by founding ,scientific evidence is offered to prevent the temperature crack and ensure the dam safe operation ,the model has some engineering valuable significance.
