Evaluating Effect of Temporary Casing on Drilled Shaft Rock Socket Friction

The primary objective of this study is to quantify the effects of temporary casing installation and extraction on the resulting side shear in the portions of the rock sockets used to embed and seal the casing. To this end, extensive literature evaluation and laboratory tests will be performed that will be verified by full scale testing.
