Relating Plastic Potential Function to Experimentally Obtained Dilatancy Observations for Geomaterials with a Confinement-Dependent Dilation Angle
Publisher: American Society of Civil Engineers
Abstract: Dilatancy (volumetric expansion) during yielding is an important aspect of geomaterial behavior that can be mathematically defined using a dilation model. A common way of modeling dilation has been to use a dilation angle, ...
Effect of Gravity of the Plastic Zones on the Behavior of Supports in Very Deep Tunnels Excavated in Rock Masses
Publisher: American Society of Civil Engineers
Abstract: The vertical load acting on a support structure is affected by the loss of self-bearing capacity of the rock inside the plastic zone. This load can then be accounted for by analytical calculation methods capable of evaluating ...
Numerical Modeling of Rock Blocks with Nonpersistent Rough Joints Subjected to Uniaxial Compressive and Shear Loadings
Publisher: ASCE
Abstract: Characterizing the mechanical behavior of jointed rocks is important to understand the behavior of structures in rock masses. Jointed rocks can be composed of persistent and nonpersistent joints where the impact of ...
Including Class F Fly Ash to Improve the Geopolymerization Effects and the Compressive Strength of Mine Tailings–Based Geopolymer
Publisher: ASCE
Abstract: Mine tailings (MTs) that are rich in aluminosilicates can be reused to create geopolymer via alkaline activation as an alternative to portland cement concrete for construction and building applications. However, pure MTs ...
