Object of study was to determine basis for wide discrepancies between laboratory test results and field values of shear strength of clay slopes; laboratory results are elucidated by means of field case records; term residual factor is used to express amount by which average strength of fissured clays decreases with time; presence of fissures and joints can lead to progressive failure in clay slope and, in limit, this process can continue until residual strength is reached, but in clays which are not fissured or jointed, decrease in strength from peak value is small or even negligible.
