The artificial neural network was introduced into the selection of piles. The important affecting elements of the selection of piles and the characteristics of BP artificial neural network were analyzed to devise network construction. An identification model of artificial neural network about the selection of piles was established based on the artificial neural network toolbox of Matlab 6.5, and the process of identification was simpler based on human-computer interactive interface by Matlab. The geology data of typical project items was input to the neural network model as practice sample, and then the model was trained and optimized. Through testing, the trained model can help designers to select an appropriate kind of piles.
