Site Investigation and Sampling Methods

  The first lecture is utilized to display photographs of typical drilling operations, Standard Penetration Testing (SPT), Cone Penetrometer Testing (CPT), and common sampling techniques (i.e., split spoon samplers, Shelby tubes, bag samples) to introduce the topic and stimulate their interest visually. The Split Spoon Sampler and Shelby Tube are passed around the classroom and one section of a hollow stem auger is displayed on a cart at the front of the classroom. Having the auger in the classroom enables the instructor to demonstrate how each sampler is introduced into the soil through the auger.
