Three-Dimensional Numerical Modelling of Al-Salam Storm Water Pumping Station in Saudi Arabia

The Al-Salam Pump Station will be constructed in the framework of Jeddah Storm water Masterplan (JSWM) in Saudi Arabia. The station discharges the incoming flow from the Al-Salam storm tunnel to the Red Sea. Its structure includes a circular deep wet well ...

Experimental analysis of a thermoactive underground railway station

Lyesse Laloui, Alessio Ferrari, Azad Koliji, Jacopo Zannin, Tohid Kazerani

Little is known about the real energy potential of thermoactive underground infrastructures, such as railway stations, that can act as a heating/cooling provider for the built environment. This study presents the results of thermomechanical full-scale in s ...

Abutment stability assessment at the Hongrin arch dam

Azad Koliji, Thierry Bussard

The Hongrin north dam is a 125 m-high double curvature concrete arch structure located in the western Swiss Prealps. A hydrogeological study and ground water monitoring revealed the presence of water pressure caused by slight seepage flow through the rock ...

Structural characterization of unsaturated aggregated soil

Lyesse Laloui, Laurent Vulliet, Azad Koliji

Despite the recent experimental studies of soil structure, a comprehensive understanding of the macroscopic response of a soil in relation to its structure has not yet been achieved. This lack of understanding reveals the need for further assessments of so ...

Constitutive modeling of unsaturated aggregated soils

Lyesse Laloui, Laurent Vulliet, Azad Koliji

A coupled water retention-mechanical constitutive model for unsaturated aggregated soils is presented here. Based on the multi-scale experimental results, the model incorporates the inter-particle bonding, fabric and partial saturation effects in a single ...

Behavior of Unsaturated Aggregated Soil in Oedometric Condition

Lyesse Laloui, Laurent Vulliet, Azad Koliji

Natural and agricultural soils usually possess an aggregated structure; in the sense that they are composed of aggregates and large inter-aggregate pores. Under the natural condition, these soils are usually unsaturated and the large pores are easily drain ...

Assessment of structural evolution of aggregated soil using neutron tomography

Lyesse Laloui, Laurent Vulliet, Azad Koliji

The advanced non-destructive method of neutron tomography, together with image analysis, is used to evaluate the structural evolution of an aggregated soil during one-dimensional compression tests. Aggregation of primary particles is a commonly observed ph ...
