AbstractInitial slides are slopes that fail under the long-term condition. Field and laboratory experiments to study the long-term behaviour of a natural slope were conducted on a bank of the Ottawa River, Ontario, Canada. The slope was instrumented with electric piezometers and continuous readings were made over a period of three years to give the long-term pore pressure distribution beneath the slope. Soil samples were subjected to various controlled stress path tests in the laboratory and field and laboratory information was used in analyzing a nearby slope failure by means of a method that accounts for progressive failure. It was later extended to other case records. As a result, a new interpretation was obtained of initial slides in Leda clay in the Ottawa region.
