Many failures and accidents in earth dams and their foundations have            been attributed to concentrated water leaks caused by cracks present in         the compacted clays forming the earth dams.  Insufficient attention has         been given by researchers of earth dam safety to the topic of                   time-dependent crack growth and interaction in stiff clays such as              those forming part of earth dams.  This will be addressed in this               project.  Specifically, the project will study in the laboratory the            mechanisms by which cracks grow and interact in prismatic samples of            brittle clay subjected to constant (creep) as well as statically                increasing biaxial and triaxial stress conditions, and study the effect         that parameters such as clay water content, number of cracks as well as         their orientation, length, separation and overlap have on the way               cracks propagate and interact in brittle clay samples.
