Seminar overview:


Molecular simulations are increasingly used to study materials of any kind, including materials relevant for civil engineering applications, such as cement or soils. But one important question is how results obtained at the atomistic scale by molecular simulations can be transferred to the macroscopic scale of the engineer.
Dr. Mattieu will compare molecular simulation results obtained at the nanometric scale of the clay layer with experiments on a clay system at a larger scale. He will focus on how moisture modifies the mechanical properties of clay at those two scales. The clay systems studied experimentally are self-standing clay films with a thickness of a few dozen microns, which are less heterogeneous than clay-based rocks but are sufficiently large to be mechanically tested with conventional techniques.

 

Biography:


Matthieu Vandamme is a Civil Engineer who has been working since 2008 at Laboratoire Navier (ENPC, CNRS, IFSTTAR) at École Nationale des Ponts et Chaussées. He is interested in materials relevant for Civil and Environmental Engineering. More precisely, his main focus lies in the mechanics and physics of porous solids. He received his PhD from MIT in 2008, for the study of creep properties of cementitious materials by nanoindentation. He is also an engineer
from Ecole Polytechnique (France) and received an M.S. degree in solid mechanics from École Nationale des Ponts et Chaussées (France). Dr. Matthieu is a French Government By-Fellow at Churchill College and a visitor at the Department of Engineering, University of Cambridge.

Seminar overview:


Groundwater is a common problem in excavations associated with basements, foundations and tunnels. If not adequately controlled and managed during construction, groundwater can cause a range of geotechnical problems, including running sands, excessive ground loss, base heave and collapse of excavations, resulting in additional costs and time delays.
However, with good planning, design and execution, below ground works can be successfully and efficiently carried out even in very challenging groundwater conditions.
This presentation provides a background to the more commonly used methods of
groundwater control and dewatering, and includes a review of the techniques used for groundwater control by pumping (sump pumping, wellpoints, deep wells, ejector wells) and for groundwater control by exclusion (cut-off walls, grouting, artificial ground freezing). Particular applications and challenges of groundwater control are discussed.

Biography:


Dr Martin Preene is a civil engineer with more than 30 years’ experience of dewatering and groundwater control with contractors and consultants worldwide and has worked extensively on major tunnel projects in the construction and mining sectors. He is widely published in the field of groundwater engineering and is the lead author of the CIRIA Report C750, the UK industry guidance on groundwater control and dewatering. He is currently the Chairman of the
British Geotechnical Association (BGA).
