This four hour online course provides guidelines for in situ testing of subsurface formations. In situ tests are used to determine the stresses and deformation behavior of rock masses and delineate critically weak seams within rock masses. Basic concepts of soil and rock behavior together with the selection of appropriate tests for construction projects are considered. In situ testing consists of geotechnical and geophysical tests. Frequently used geotechnical tests for shear strength, bearing capacity, stress conditions, deformability and liquefaction susceptibility include the standard penetration, cone penetration, direct and vane shear tests. Strength tests include unconfined compressive, triaxial, and shear. Also covered are geophysical tests, mechanical wave and electromechanical methods, used to delineate subsurface conditions, top of rock mass conditions and for locating buried objects, pipes, and cavities. Problem soils such as clay shales and rock formations with weak seams and jointed masses are discussed for consideration of construction projects. Guidelines for testing procedures and storage and handling of specimen samples along with the ASTM designations for the most frequently used in situ tests are noted.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
