To overcome the shortcomings of the methods used in comprehensive assessment of earthquake destruction, a new method, named projection pursuit PP model was presented. The evaluation indexes values of each sample were synthesized as projection value with one dimension which indicates the destruction degree. The improved ant colony algorithm was employed to predigest the realized process of projection pursuit technique. Engineering practice shows that the model can realize the simple, objective and feasible assessment. This work has significance for the decision making of the succoring and rebuilding after the earthquake.
