Based on the safety observation data of dam, the establishment of the prediction model of dam deformation is very important for safe operation of the reservoir. The early deformation curve of the dam has self-similar fractal feature. The fractal interpolation function can be applied to not only processing the dam prototype observation data but also forecasting the rule of early dam deformation. In this paper, the reservoir dam deformation can be analysed and predicted by the fractal interpolation function. Analysis shows that, the method for dam deformation prediction of maximum error is 8.0%. Therefore, regarding the half-year short-term forecast, the forecast result obtained from fractal interpolation function method could be reliable.
