Presentation Long-term Bond Characteristics of the Interface Between Substrate and Shotcrete Overlay Shotcrete is becoming popular for vertical and overhead applications where conventional formwork and repairs are difficult and costly. However, the substrate and the shotcrete overlay interface can be vulnerable, and the bond properties in this region are not well understood. Furthermore, the interface […]

Presentation Rock Failure Process Analysis A major difficulty in studying the fracture mechanisms for rock subjected to various loads is the fact that rock is a natural, composite material which is Discontinuous, Inhomogeneous, Anisotropic and Not Elastic (DIANE). It is not possible to analytically examine and evaluate the mechanical behavior of a DIANE rock exhibiting […]

Presentation Recent Advances in Measuring Volume of Soil Specimen in Triaxial Testing Triaxial tests have been widely used for measuring the stress-strain behavior of both saturated and unsaturated soils. Volume/displacement measurement is an indispensable component of the triaxial testing. This paper provides a state-of-the-art review on the existing methods to measure volume change and/or displacement […]
