| Abstract: | According to data mining and the basic theory of chemical thermodynamics,a program based on FORTRAN code and a determined method for optimal model threshold is designed.In accordance with different calculation aim,selecting different target ion respectively is used as threshold of control model cycling.In combination with a concrete project example,compared with traditional algorithm,it is proved that this model algorithm has better stability and calculation precision for dam address area calculation. |
| Keywords: | dam-base stability data mining principal component analysis model threshold saturation index(SI) |
