Poisson Curve is applied to high-rise building settlement forecast.Unequal time interval data is transferred to equal time interval data with using Newton Interpolation.The model factors are calculated with 3 block method.By comparing with measured data,it is shown that Poisson Curve forecast data and the actual settlement data agree well,and curve fitting accuracy is high.Its effect is better than the methods of hyperbola and exponential curve.This forecast method has a high value in practical applications.
