Further Study on Forecasting Model of Main-dam's Deformation

Directing the problems of the forecasting model of main-dam's deformation based on sing-factor or mutiple-factor,a sort of forecasting model of main-dam's deformation is put forward which has higher-precision than others through the injection of two independent variables,water level and time.The adoption of coefficient,bidirection optimun seeking methed are adopted.This forecasting model has been compared with quadratic sum of suplus difference,standard suplus difference and pertinent index number.
