- Abstract
Lime is widely used for soft ground treatment, rendering the compressibility of lime-treated soil a crucial factor in deformation analysis in engineering applications. This study investigated the compressibility of three remoulded lime-treated slurries with high water content in Southeast China. Sixty groups of oedometer tests were conducted on lime-treated soils with an initial water content of 1 to 3 times the liquid limit and lime contents between 1 and 3%. The oedometer test results were discussed to examine the remoulded yield stress σ y ′ of lime-treated slurry. Considering the relationships between σ y ′ , the void ratio, lime content, and initial water content were preliminarily discussed and quantitatively established. Research on the normalised compression curve of lime-treated soil revealed that for soil samples containing a lime content of 0–%, the normalised compression curve at σ p ′ > σ y ′ can be represented by a unique line. Furthermore, the log(1 + e) − log σ v ′ compression curve of lime-treated slurry at pre-yield state is analysed, and a prediction method for the modified compression index is proposed.
