1.1 INTRODUCTION. Reliable estimates of the strength and deformation characteristics of rock masses are required for almost any form of analysis used for the design of underground excavations. Hoek and Brown (1980a, 1980b) proposed a method for obtaining estimates of the strength of jointed rock masses, based upon an assessment of …Web

Although the DT algorithm is useful in many civil engineering cases, a more powerful approach, the RF algorithm, was proposed by Breiman and has been proven to be more robust in many data mining problems than a single tree (Kuhn and Johnson 2013; Qi et al. 2017; Qi and Tang 2018).RF is an ensemble learning technique that builds on …Web
