Field Strength of Soils in Relation to Texture and Moisture Content

Abstract

Strength profiles of in situ soil representing different textual groups except silt have been established by measuring cone index values at the surface and thereafter successive depth intervals of 3 inch upto a maximum depth of 24 inches at 92 sites during dry and wet seasons. In wet state clayey and silty soils lose nearly half of their original strength. Most soil types show a progressive increase in strength with increase in depth in both dry and wet states.
