Visit from Prof. Aronne Armanini

From left to right: Prof. Clarence Choi, Prof. Charles Ng, George Goodwin and Prof. Aronne Armanini

Prof. Ng’s research group was very fortunate to have the company of Prof. Aronne Armanini of the University of Trento (in Italy) for several days in August. Prof. Armanini gave a fascinating seminar, covering topics such as how different types of geophysical flows may be quantifiably differentiated using rheological properties, as well as the governing equations that must be used to describe mixtures of grains and viscous fluids. He also discussed some of the mitigation measures for geophysical flows that are installed in Europe, covering how their effectiveness can be quantified and showing examples of undesirable designs.

New paper: Back-analysis of geophysical flows using a 3-dimensional runout model

The journal paper Back-analysis of geophysical flows using a 3-dimensional runout model has been accepted for publication in the Canadian Geotechnical Journal. The finite-element software package LS-DYNA was used to calculate the internal friction angle of a series of debris flows in Hong Kong. Read the full article here.

Modified pressure plate apparatus

Schematic of the modified pressure plate apparatus

The modified pressure plate apparatus is used to study the volume change behaviour of unsaturated soils (Ng et al. 2002). Prior to its development, measurements of the volume change had limited accuracy.

New paper: Dry granular flow interaction with dual-barrier systems (Géotechnique)

The Géotechnique paper Dry Granular Flow Interaction with Dual-barrier Systems is now available online. Both small-scale flume tests and the finite-element package LS-DYNA were used to understand multiple mechanisms of interaction between flows and dual-barrier systems.
