Shear strength regain tests of clayey soils

The shear strength regain effect takes place whenever an intermittent landslide on clayey materials occurs.During the rest period, the clay material nearby the sliding surface regains part of its shear strength. The new strength level can overcome the residual shear strength by more than 20%. The more is the rest period, the more is the shear strength regain. The paper examines closely the shear strength regain phenomenon, analysing the results derived from several dedicated ring shear tests on clayey landslide materials, and deals with the accordance of the laboratory tests with field situations.
