The stress-strain relationship of soils, and therefore the shearing strength, is affected (Poulos 1989) by: 1. soil composition (basic soil material): mineralogy, grain size and grain size distribution, shape of particles, pore fluid type and content, ions on grain and in pore fluid. 2. state (initial): Defined by the initial void ratio, effective normal stress and shear stress (stress history). State can be describe… WebThe dynamic shear strength of rocks is required for the earthquake-resistant design of nuclear power plants in Japan. This research aims to propose a mathematical model for estimating the dynamic ...
