Well, what is the strength of unsaturated clay?

Richard Herraman

Talking Points

There are several equations for the shear strength of unsaturated clay. Which is best? How do you get the numbers to put into them? How do you use them for design? This talk is a journey, starting with a trip down memory lane, traversing steep cuttings while retaining a sense of humour, then landing on firm footings and ending with surprises.
