Abstract:
This paper presents a method for simply qualifying the practical
risk of casting deep foundations based upon a combination of the
behavior of the fresh concrete through testing and the confinement
conditions of the foundation from a design perspective.
A framework to qualify which aspects of the tremie process lead
to defects is developed for the first time. Flow behavior, confinement
conditions, and free-water availability are identified as key
contributors to specific defects present within tremie concrete foundations. Finally, a novel risk map for tremie concrete is presented.
