TP – 1308 An Introduction to Foundations on Unstable Soil Conditions for Professional Engineers

Description

Many types of soils change volume from causes different from elastic deformation, consolidation, and secondary compression. These volume changes cause excessive total and differential movements of overlying structures and embankments in addition to load induced settlement of the soil. Such unstable conditions include the heaving of expansive clays and collapse of silty sands, sandy silts, and clayey sands from alteration of the natural water content. Adequate engineering solutions such as special foundation designs and soil stabilization techniques exist to accommodate the anticipated soil movement.
