Abstract


Abstract: The present study aims at modeling the scour depth around circular bridge piers in Algeria (semi-arid zones) by Artificial Neural Networks (neuroemulation). In the pretreatment phase, the reduction of the dimensionality of the inputs to the neuronal model is performed by the classical linear method: Principal Component Analysis (PCA). The results obtained for this type of data showed that PCA provides very powerful models.

Résumé : La présente étude a pour objet la modélisation de la profondeur d’affouillement autour des piles de pont circulaires en Algérie (Zones semi-arides) par Réseaux de Neurone Artificiels (neuro- émulation). A la phase de prétraitement, la réduction de la dimensionnalité des entrées au modèle neuronal est effectuée par la méthode classique linéaire : l’analyse en composantes principales (ACP). Les résultats obtenus pour ce type de données ont montré que l’ACP fourni des modèles très performants.
