INFLUENCE OF HORIZONTAL STRESSES ON GILGAI LANDFORMS. TECHNICAL NOTE

"Normal gilgai" is a term used for landforms with a sine-wave symmetry of mounds and depressions. Gilgai landforms occur in expansive clays and probably cause undulations in pavements. The presence of naturally occurring horizontal stresses in overconsolidated expansive clays is likely to be the cause of these extreme movements, which alter the normal vertical stresses in a prebuckling mode and produce a differential vertical rebound. The behavior of gilgai and their associated shear fractures support this theory.
