Project: Polymer soil interactions in geo-technical processes
Sponsor: EPSRC CASE with Stent Foundations
My research deals with the use of synthetic polymer fluids for the construction of structural
foundation elements such as bored piles or diaphragm walls. These fluids are typically solutions of
partially hydrolysed polyacrylamide (HPAM or PHPA) or more complicated polymer blend. Although this
construction technology has been used in various parts of the world for almost two decades, very little
is known about the relationships between the physiochemical properties of the polymer fluids and the
load-settlement behaviour of the foundation. The aim of this research is to improve our understanding
in the following areas:
-
Fundamental difference between the various polymer products available in the market
-
Rheological properties of the polymer fluids
-
Field techniques for measuring the properties of polymer fluids
-
Relationship between fluid and soil properties and hence the effects on foundation behaviour
