Application of "effective" stress principles in the prediction of heave in unsaturated expansive clay requires an evaluation of the swell index and changes in the matric suction. The latter, in turn, requires knowledge of water balance principles. This paper presents a case study to illustrate the practical application of an effective stress approach to heave prediction. The purpose of th…
Adequate design of post-tensioned residential slab-on-ground foundations in expansive soils is dependent on understanding the geotechnical and climatic factors inherent to the procedure. A method for design of ground-supported slab foundations was developed by the Post-Tensioning Institute (PTI). The design stiffness factors (edge moisture variation distance, em, and differential movement, ym) …
