报告人简介：

Directeur de Recherche CNRS (French National Center of Scientific Research). Leader of OID Group (Sustainable Structures and Infrastructures), Laboratoire de Tribologie et Dynamique des Systèmes (UMR-CNRS 5513), Université de Lyon, ENTPE.

Henry K.K. Wong got his Diplôme d'Ingénieur from ENTPE (French Nat. School of State Public Works) and MSc of INSA-Lyon in 1984 before joining Simecsol (French Geotechnical Consultant) as design engineer and became branch office director in Singapore in 1988. He intervened in many civil engineering projects (Singapore Central Expressway, Taipei Automatic Railway, French National Railway and Stations...). After obtaining his PhD in 1994 on the thermal-mechanical behaviour of underground nuclear waste repositories, he joined CNRS (French National Scientific Research Center) and worked in LGCB/LTDS-ENTPE (ass. to CNRS) since 1995 and became a research professor there since 2005. His current research activities concern the multiphysics behaviour of porous materials and geostructures: unsaturated and quasi-saturated soils; rammed earth; soft rocks; underground storage structures, earthen buildings.

报告简介：

Most of the materials used in civil engineering constructions are porous (soils, rocks, rammed earth, concrete, etc.), filled with different pore fluids: water and/or air for most applications, but can also be liquid oil or super critical CO2, etc.). The presence of pore fluids affects significantly the mechanical behaviour of the the solid skeleton. Inversely, changes of the skeleton properies modify the transport kinetics of pore fluids. Phase changes such as transformation between ice, liquid water and water vapour have a decisive impact on the overall behaviour. Moreover, changes in the pore fluid chemical content (concentration of neutral solutes or electrically charged ions) also affects the overall behaviour. Different situations that are problem-dependent intervene in civil engineering. This presentation presents some of the research works undertaken in LTDS concerning unsaturated soils and rammed earth.
