Webfied relationship between relative density, effective confining stress and peak friction angle. Been and Jefferies (1985) combined in-situ void ratio and effective confining stress to develop a state parameter ( ) to capture the in-situ response of sands and showed that more accurately represents in-situ state for sandy soils. Plewes et al WebFor any building foundation, design and construction soil testing are essential. The test is extremely useful for determining the bearing capacity, density, and angle of shearing resistance of any soil. It can be used to determine the properties of cohesive and cohesionless soil. The Standard Penetration Test ASTM D1586-11.
