DOI: 10.1007/s12665-017-6473-4
Abstract: The progressive failure of slopes is often induced by drawdown and strain-softening of the soil. Thus, the stability level of a strain-softening slope under drawdown conditions should be evaluated while considering progressive failure. A simplified… read more here.
