Abstract: The strength envelopes of almost all types of rocks are nonlinear over a wide range of normal stresses. This paper presents a study in which the nonlinear Hoek-Brown failure criterion was adopted and the kinematical approach ...

Abstract: The three-dimensional (3D) stability calculations of soil slopes are often focused on homogeneous soils in the published literature. However, strength inhomogeneity is a common phenomenon in slope engineering. The purpose ...

Abstract: A linear failure criterion is widely used in slope stability analyses. However, the strength envelope of almost all geomaterials has the nature of nonlinearity. This paper computes rigorous upper bounds on slope stability ...

Abstract: Economic development and the related increase in global energy demands have created pressure on the supply of energy resources. To promote sustainable development, a safe and renewable energy is required. For this, wastewater ...
