Experimental Investigation on Mechanical Properties of Cemented Expansive Soil
Expansive soil has the characters of swell-shrink, fissured and over-consolidated, which can affect the safety of construction projects in expansive soil areas. Deep soil mixing (DSM) is a widely used ground improvement method. It can improve the mechanical properties and reduce the permeability of expansive soil effectively. In this study, a series of direct shear tests and unconfined compressive tests were conducted to study the effect of cement content and curing time on the mechanical properties of cemented soil. Relationship among the mechanical properties and cement content and curing time were analyzed qualitatively and quantitatively by the test results. Recommendations for design and construction of the DSM in expansive soil areas were also proposed in this study.
