Abstract: Project risk prediction is a very important issue，project managers very concern about it.But there is not a method accepted by most of the scholar until today.This paper tries to use AntClust algorithm to resolve this problem and through a numerical example to explain the whole process，the result of the indicating is good.It finds out that compared with SVM the AntClust algorithm has the characteristics of simple operation.
