For the optimal selection of pile foundation scheme, the optimal selection method of pile foundation scheme is established based on fuzzy analytic hierarchy process(AHP), and the optimal selection procedure of pile foundation scheme is given. The AHP is used to determine the weight of evaluation index,and the fuzzy theory is used to carry out the comprehensive evaluation. Through a case study, the application of the proposed method in practical engineering is illustrated. The practice has proved that this method has good operability in practical application. The optimal selection method of pile foundation scheme can consider the multi-objective decision model and select the most ideal pile foundation scheme.
