Prediction of slope stability using artificial neural network (case study: Noabad, Mazandaran, Iran)

Abstract

Investigations of failures of soil masses are subjects touching both geology and engineering. These investigations call the joint efforts of engineering geologists and geotechnical engineers. Geotechnical engineers have to pay particular attention to geology, ground water, and shear strength of soils in assessing slope stability. Artificial neural networks (ANNs) are very sophisticated modeling techniques, capable of modeling extremely complex functions. In particular, neural networks are nonlinear. In this research, with respect to the above advantages, ANN systems consisting of multilayer perceptron networks are developed to predict slope stability in a specified location, based on the available site investigation data from Noabad, Mazandaran, Iran. Several important parameters, including total stress, effective stress, angle of slope, coefficient of cohesion, internal friction angle, and horizontal coefficient of earthquake, were used as the input parameters, while the slope stability was the output parameter. The results are compared with the classical methods of limit equilibrium to check the ANN model's validity.Keywords Slope stability . Artificial neural network . Nonlinear .

Application of several non-linear prediction tools for estimating uniaxial compressive strength of granitic rocks and comparison of their performances

“…Different learning rate values have been proposed by several authors. Learning rates of 0.05 and 0.5 were suggested in the studies conducted by Jahed Armaghani et al [42] and Choobbasti et al [79], respectively. Yilmaz and Yuksek [56], Erzin and Cetin [80] and Momeni et al [81] recommended the value of 0.01 for learning rate, while this value was suggested as 0.1 in the study conducted by Yagiz et al [65].…”

Unsaturated Soils: Research and Applications

“…If it's correct, the neural weightings that produced that output are reinforced; if the output is incorrect, those weightings responsible are diminished. This type is most often used for cognitive research and for problem-solving applications (Choobbasti et al 2009). …”

“…One of the most well-known FF-ANN is multilayer perception (MLP) neural network. An ANN architecture (Figure 1) is invented of an input layer, an output layer and one or more hidden layers [9]. Back-propagation (BP) networks learn from continuing existence, and its characterization gained wide application in civil engineering [10].…”
