Abstract: Artificial Neural Network (ANN) and Adaptive Neuro-Fuzzy Inference Systems (ANFIS) models are used to predict the external stability of cantilever reinforced concrete (RC) retaining walls. A total of 235 different designs of cantilever RC retaining walls using procedure of BS: 8110 were used. Three input parameters were used namely; height of wall, angle of slope, and surcharge, while the output parameters consist of the external stability namely: factors of safety (FOS) for sliding, overturning and bearing capacity. The output data generated through design is used as a target for both models. Two criteria involving the determination coefficient (R2 ) and root mean square error (RMSE) were used to evaluate the accuracy of prediction models. The results showed that prediction made using ANFIS more accurate compared with ANN.
