Abstract: This paper presents the hydraulic characteristics of an unsaturated, compacted clay, including its soil-water retention curve (SWRC) and hydraulic conductivity function (

Abstract: A new centrifuge permeameter was developed with the specific objective of expediting the measurement of the hydraulic characteristics of unsaturated soils. The development, theoretical basis, and typical results associated ...

Abstract: A constitutive model is presented in this paper to describe the isotropic compression response of unsaturated, compacted clay under drained conditions over a wide range of mean effective stresses. The model captures the ...

Abstract: This study focuses on the use of a thermomechanical soil-structure interaction (load transfer) analysis to assess the axial strains, stresses, and displacements during thermomechanical loading of energy piles in various ...

Abstract: The roles of particle breakage and drainage conditions on the quasi-static compression response of sand were evaluated by comparing the results from drained and undrained isotropic compression tests on dry and saturated ...

Abstract: This paper examines the effects of monotonic and cyclic temperature changes of a model energy pile (diameter=25  mm, length=264  mm) on the variations in temperature and volumetric water content of surrounding unsaturated ...

Abstract: This paper presents a heat transfer model for thermo-active drilled-shaft foundations used for heating and cooling buildings. Specifically, this paper presents a numerical approach to evaluate the ...
