The Science of Soil Mechanics & Holding Capacity

Posted by Tim Staelens on Jul 23, 2018 3:41:00 PM

Historical Analysis

During the early development of the screw anchor, the load resistance of an installed anchor could not be predicted with adequate accuracy. Specific information on soil conditions was lacking, making anchor selection more or less a guess. With little consideration for soil variations, the effects of seasonal weather changes or drainage, soils were classified as: either sand, clay, hardpan or swamp. At that time, there was not a definitive explanation for the soil conditions.
