“…There has been cumulatively a large amount of laboratory and site investigation of the behaviour of soils treated in this way, but there are few systematic and theoretical studies of the mechanical properties of lime-treated soft clay that are applicable to practical problems (e.g. Boardman et al, 2001;Horpibulsuk et al, 2010;Liu et al, , 2010Locat et al, 1996;Suebsuk et al, 2010Suebsuk et al, , 2011. The lime stabilisation leads to a rise in the pH of the pore water and dissolution of the silica and alumina from the clay, in a manner similar to the reaction between a weak acid and strong base.…”

Strength is often the most significant parameter in measuring the effect of soil improvement in geotechnical engineering practice. In this paper, a primary study is made of the variation in unconfined compressive strength of lime-treated soft clays under various practical conditions. There are three major factors that affect the strength NotationA w ratio of lime to clay by weight, both in dry state A w,max optimum lime content a rate of strength increment in the logarithmic t scale q shear stress q 0 strength of the untreated soil q max maximum unconfined compression strength q T0 strength at T ¼ 08C T curing temperature t curing time AE Aw material parameter describing the influence of lime content AE T material parameter describing the influence of curing temperature AE t material parameter describing the influence of curing time AE w material parameter describing the incremental rate of increase in strength with lime content

“…A brief introduction of the extended model is given below, and details of the model can be found in papers by Liu and Carter [9] and Horpibulsuk et al [6]. Modification of the mean effective stress cementation A fundamental assumption in the extending the SCC model for the effect of cementation is taken into consideration as the reinforcement of the confining mean effective stress; and a modified mean stress parameter is proposed as follows,…”

The behaviour of collapsible soils (loess) is studied in this paper. Simulations of the stress and strain behaviour of the soil are made via the theoretical framework of Structured Cam Clay, with the effect of glutinous ingredient in loess suggested to be modelled as cementation effect. Based on the simulations, the capacity of the model for representing the behaviour loess is investigated, and discussions on modelling the behaviour of collapsible soil in general are given.

“…The effect of the field mixing parameters, such as installation rate, water/cement ratio and rate of rotation on the strength development of soil-cement columns were investigated by Nishida et al (1996) and Horpibulsuk et al (2004c and2011b). Based on the available compression and shear test results, many constitutive models were developed to describe the engineering behavior of cemented clay (Kasama et al, 2000;Horpibulsuk et al, 2010;Suebsuk et al, 2010 and2011 etc).…”

Finite element analysis of consolidation behavior of composite soft ground AbstractColumnar inclusion is one of the effective and widely used methods for improving engineering properties of soft clay ground. This paper investigates the consolidation behavior of composite soft clay ground using both physical model tests under an axial-symmetry condition and finite element simulations using the PLAXIS 2D program. Because the soil-cement column enhances the yield stress and stiffness of the composite ground, the composite ground is in an over-consolidated state under the applied vertical applied stresses. At this state, the rate of consolidation is rapid due to a high coefficient of consolidation. The consolidation of the composite ground is mainly controlled by the area ratio, the ratio of the diameter of the soil-cement column to the diameter of the composite ground, a . As the area ratio increases, the rate of consolidation increases and the final settlement decreases.
