A method for evaluating the strength of the in-situ cement-treated soils is proposed based on the two-phase mixture model. The in-situ treated soil is regarded as a mixture which consists of the improved parts, so that the deformation modulus and the unconfined compressive strength are quantitatively estimated by taking account of the stress distribution and the stirring mix rate in the mixture. In order to confirm the validity of the propose method, the model tests and the in-situ tests were carried out. It may be concluded that the proposed method is capable of predicting the strength of the in-situ treated soils with a certain stirring mix rate by using those of the laboratory mixed soil and the in-situ original soil.
