SOIL WATER AND ITS EFFECT ON SOIL ENGINEERING PARAMETERS

GAPS IN THE KNOWLEDGE OF SOIL ENGINEERING PARAMETERS AND PARTICULARLY THE EFFECT OF WATER ON THESE PARAMETERS ARE DISCUSSED. IT IS EMPHASIZED THAT THE PERFORMANCE OF THE STRUCTURE AT THE BROAD PRACTICAL LEVEL DEPENDS ON A SINGLE PARAMETER OF THE SOIL IN SITU WHICH IS A FUNCTION OF THE SOIL TYPE AND THE SOIL WATER POTENTIAL. IN THE CASE OF HIGHWAY PAVEMENTS, THE PARAMETER IS THE DYNAMIC STRESS- CONTROLLED DEFORMATION CHARACTERISTIC AS A FUNCTION OF THE SOIL WATER POTENTIAL, WHEREAS FOR HOUSE DWELLINGS IT IS GENERALLY THE DEFORMATION CHARACTERISTIC UNDER CONSTANT STATIC STRESS, ALSO AS A FUNCTION OF THE SOIL WATER POTENTIAL. IT IS SHOWN THAT THE CONTROLLING SOIL WATER POTENTIAL IS GOVERNED ENTIRELY BY THE POTENTIAL GRADIENT BELOW THE DEPTH OF SEASONAL MOISTURE VARIATION. THE ENGINEERING PERFORMANCE OF THESE STRUCTURES CAN BE DETERMINED ONLY FROM LAND EVALUATION PROCEDURES WHICH DELINEATE ON THE EARTH'S SURFACE AREAS OF SIGNIFICANTLY DIFFERENT SOIL TYPE AND SUBSURFACE MOISTURE CONDITIONS. /AUTHOR/
