Abstract A reliability model of shear strength of rocks and soils from test data is proposed. The model possesses special advantage for limited test samples. The shear strength parameters, and c,generally are of two dimen- sional probability distribution with strong negative correlation. Using this reliability model,one single guaranteed factor can be used to determine uniquely the design values of and c.
