Chair holder’s Areas of expertise

Embankment dams
Behaviour and characterization of construction materials
Hydric, thermal and mechanical properties of construction materials
Behaviour modelling of embankment dams

Objectives

  • Provide better understanding of the behaviour of materials used for the construction of embankment dams
  • Characterize the hydric, thermal and mechanical behaviours of embankment dam materials
  • Model and predict the behaviour of embankment dams under normal and exceptional solicitations such as earthquakes
  • Facilitate the interpretation and representation of data collected during the monitoring of the dams
  • Develop selection criteria for different materials in order to optimize the dams’ life service
  • Establish critical threshold of seismic behaviour for the inspection of embankment dams

According to the International Commission on Large Dams (ICOLD), 75 % of dams built in the world are embankment dam (earth dams). The imperviousness of embankment dams is assured by fine granular materials put in place or by an impervious element. As the construction of embankment dams involves granular materials found near the construction sites, those dams represent a top choice for remote areas.

Embankment dams performance and life span are closely related to the hydric, thermal and mechanical behaviour of materials from which they are built. The apparent simplicity of embankment dams hides complex and often poorly understood behaviour resulting from thermo-hydro-mechanical coupling phenomena. Understanding the different behaviours as well as their relationships is of paramount importance to optimize the life cycle of these structures.

Mission

Develop tools to analyze and predict the behaviour of embankment dams through:

  • a deeper understanding of the behaviour of materials used in the construction of embankment dams
  • the development of an effective system to process data collected during the monitoring of existing structures to develop robust and reliable modelling tools

Research impacts  

The benefits generated by the second phase of the NSERC/Hydro-Québec Industrial Research Chair on Life Cycle Optimization for Embankment Dams will be important for the partners and for the entire Canadian society.

A better understanding of the thermic, hydric and mechanical behaviour of construction materials will improve the design of embankment dams, avoiding subsequent default correction works, which represent important spending because of the remoteness associated with such structures. Furthermore, the development of dynamic analysis tools will greatly help to evaluate the behaviour of embankment dams subjected to seismic solicitations.
