Multilayer-perceptron-based prediction of sand-over-clay bearing capacity during spudcan penetration
Ding Kailin,Fan Shuntao,Dong Sheng 대한조선학회 2022 International Journal of Naval Architecture and Oc Vol.14 No.1
A method combining a multilayer perceptron and Large-Deformation Finite-Element (LDFE) analysis is proposed for addressing large errors in conventional formulations and time-consuming numerical simulations for predicting the bearing capacity of sand over clay during spudcan penetration. The method yielded accurate bearing capacity curves, agreeing well with the LDFE and centrifuge test results. The method can be used for quickly and accurately predicting the bearing capacity curves and for generating various data samples for theoretical studies of the effects of spudcan penetration into sand over clay on the bearing capacity. The critical depth of the bearing capacity curve was revised based on several samples generated using the method, and the result was used for fitting the bearing capacity curve. The fitted equations in this study yielded high-accuracy predictions for different scenarios.
