Hydro-mechanical behavior of unsaturated specimens isotropically reconstituted from slurry and compacted specimens

Ahmadi Naghadeh, Reza
Response of unsaturated soils constitutes an important consideration for many problems in geotechnical engineering. The main objective of this study is to understand coupling hydro-mechanical behavior of the unsaturated reconstituted specimens from slurry and moist-tamped compacted specimen, and to develop practical and cost-effective testing equipment and procedure. The innovations that will be put forth by this study will make the unsaturated soil mechanics more accessible and appealing to those practical engineers working. A prediction type exponential equation is introduced to predict the shear strength of the unsaturated soil. Equation involves three constant parameters. Two of which are effective shear strength parameters (i.e. ϕ́ and ć can be determined through conventional saturated shear strength tests). The third parameter is ultimate shear strength.
