Neural network prediction of the reliability of heterogeneous cohesive slopes

Abstract

Summary The reliability of heterogeneous slopes can be evaluated using a wide range of available probabilistic methods. One of these methods is the random finite element method (RFEM), which combines random field theory with the non‐linear elasto‐plastic finite element slope stability analysis method. The RFEM computes the probability of failure of a slope using the Monte Carlo simulation process. The major drawback of this approach is the intensive computational time required, mainly due to the finite element analysis and the Monte Carlo simulation process. Therefore, a simplified model or solution, which can bypass the computationally intensive and time‐consuming numerical analyses, is desirable. The present study investigates the feasibility of using artificial neural networks (ANNs) to develop such a simplified model. ANNs are well known for their strong capability in mapping the input and output relationship of complex non‐linear systems. The RFEM is used to generate possible solutions and to establish a large database that is used to develop and verify the ANN model. In this paper, multi‐layer perceptrons, which are trained with the back‐propagation algorithm, are used. The results of various performance measures indicate that the developed ANN model has a high degree of accuracy in predicting the reliability of heterogeneous slopes. The developed ANN model is then transformed into relatively simple formulae for direct application in practice. Copyright © 2016 John Wiley & Sons, Ltd.

An Automatic Monitoring Method of Slope Deformation in Open-pit mine based on BP Neural Network and GIS Technology

“…The stress deformation and trend of the side slope of open pit mine are controlled dynamically in real time. And the nonlinear artificial intelligence algorithm, neural network and other mathematical models are used to automatically monitor the slope deformation of open-pit mine, which has important theoretical value and popularization and application significance [4].…”

Slope stability analysis using recent metaheuristic techniques: a comprehensive survey

“…Moreover, the hybridisation of these algorithms, such as CS with boundary constraint (CS-EB) [51], PSO with HS (PSO-HS) [52], ACO with simulated annealing (ACO-SA) [53], and GSA with sequential quadratic programming (GSA-SQP) [54] are used. Furthermore, artificial neural networks (ANNs) [55][56][57][58][59][60][61][62][63][64], reliability index [65] and fuzzy logic [66] have also been used to analyse the stability of slopes and earth dams. These studies indicate the potential of metaheuristic algorithms for assessing slope stability.…”
