ANFIS model for predicting deformation of dam

In forecasting deformation of dam,many influential factors exist as well as interrelation of factors was complex.Hence, general simulation functions are difficultly to meet the needs of safety supervising of dam.As we know,adaptive neural-fuzzy inference system(ANFIS)has good capability of fuzzy system and artificial neural network.Influential factors of deformation of diaphragm wall analyzed systemically as well as effects of temperature,time,and water level of reservoir considered,predicting model of deformation of dam is established based on ANFIS.Taking the second stage cofferdam of Three Gorges Project for example, the studies are carried out with this model.The results show that the model is simple in calculation and good in applicability and precision,so as to provide a new method for forecasting deformation of dam.
