University of Missouri – Columbia Civil and Environmental Engineering Q-TYPE TRIAXIAL COMPRESSION TESTS Purpose The purpose of this lab is to teach you how to perform Q-type triaxial compression tests. This type of test is widely used in engineering practice, particularly to supplement unconfined compression tests. Q-type triaxial tests are especially useful for fissured and slickensided clays, e.g., the Beaumont formation which underlies much of the Houston, Texas, area, because the confining pressure tends to close any open fissures. For example, the following shear strength data were obtained an various strata within the Beaumont formation at the site occupied by the South Texas Nuclear Power Plant: Average Undrained Shear Strength (psf) Clay Layer Unconfined Comp.

However, the procedure that we will use will differ from that described in your book. The following procedure should be
