Abstract:

Inshore saline soil can be solidified respectively and jointly with cement, lime, flyash and polymer SH agent for increasing the anti-deformation and the strength in air and water of the solidified soils. Triaxial compression test of six solidified soils have been carried out for studying the deviatoric stress-strain properties of the solidified soils. Generally, the deviatoric stress-strain curves of solidified soils with cement and lime and that with lime and flyash are strain softening; that with lime are strain hardening. On the basis of the results of triaxial compression test, SH agent can increase the strength of solidified soil in air and water; furthermore, the strain can be increases at the maximum strength, i e. anti-deformation and elasticity of solidified soil is enhanced. It has been proved that the solidified soil with 0.9% SH agent and 12% lime and 36% flyash has the well properties, such as lightweight soil, higher strength, and well elasticity, in addition, it can decrease settlement of road foundation because of the lightweight soil.

Key words: inshore saline soil, solidified soil, deviatoric stress-strain, triaxial compression test, solidified material
