Predicting Stability of Slope by Amplitude and Coherence Using a Naïve Bayes Classifier

Abstract

Slope instability is a challenge in both mining and civil engineering industries. Current ap-proaches to slope stability analysis are mostly based on slope deformation data provided by mon-itoring equipment. This study proposes a new method to estimate slope stability using amplitude and coherence obtained from slope stability radar data. More than 160,000 data points from 10 slope failures were collected with GroundProbe’s slope stability radar systems. They were used as input dataset in a Naive Bayes model for classification into two groups of stable and unstable slopes. The classifications were conducted based on different range limit values for amplitude and coherence. The findings were validated against slope deformation behavior in each case. The results show that 91 percent of the data that are classified as unstable slope by the Naive Bayes Gaussian method belong to slope failure events and are categorized correctly. The coherence and amplitude range values proposed in this research can be utilized by mining operations to determine the stability of slopes in conjunction with slope deformation and inverse velocity data.

“…Alteration zones in this region are seen in relation to Eocene-Oligocene volcanic and around the location of faults and fractures. Alteration zones include argillic alteration in the center and west of the area, siliceous in the center and parts of the south of the area, and carbonation (Malekian et al 2022). In general, the main structural control faults of the region can be divided into two general categories, which include, 1) Northwest-southeast faults that these faults have a greater role in determining the structural status of the region than the second category faults and they often have a non-slip function, and 2) faults with north, northeast-south, southwest, which are more of normal slip slope.…”
