Web12 mrt. 2024 · This paper proposes an analytical approach for assessing rock slope stability based on a three-dimensional (3D) Hoek–Brown (HB) criterion to consider the effects of intermediate principal stress. The 3D HB criterion, considering an associate flow rule, is utilized to describe the perfectly plastic behavior of rock mass under a plane strain … Webfold, in geology, undulation or waves in the stratified rocks of Earth’s crust. Stratified rocks were originally formed from sediments that were deposited in flat horizontal sheets, but in a number of places the strata are no longer horizontal but have been warped. Sometimes the warping is so gentle that the inclination of the strata is barely perceptible, or the warping …
