Abstract

Asize effect on the strength of cement-treated soils is studiedtheoreticallybased on a newprobabilistic failure model in which a weakest link model and a bundle model are combined. The proposed model expresses not onlythe size effect on the strength ofthe specimens with the different volume but also the difference of slenderness ratio in the diameter and height. In order toconfirm the validity of this model, unconfined compression, splitting tensile and bending tests were performed. The calculated results obtained from this model arecompared with thesetest results and the previous experimental results of the cement-treated soils. This method is also applied to cement-treated soil columns made by Deep Mixing Method and the unconfined compressive strength of the columns is predicted from the strength and the coefficient of variance on a small size specimen in laboratory.
