An Explanation for the Delayed Failures of Natural Slopes and Earth Dams
Slopes and earth dams made of stiff clay can fail after many years of their construction. The delayed failure of these structures has been explained by: (1) the pore pressure equilibration within the stiff clay; and (2) the creep induced structural breakdown of the stiff clay. These explanations assume the stiff clays involved in the failure of the earth structures to be intact. However, the majority of stiff clays contain fissures. The role of these fissures on the delayed failure of slopes and earth dams made of stiff fissured clay has not been investigated to date. Under constant gravitational stresses (creep), the fissures in the clay could slowly propagate and interact producing as a result the failure surface that causes the delayed failure of these earth structures. In this study, the delayed failure of slopes and earth dams is explained by the creep propagation of the fissures in the clay.
