Triaxial Testing Fundamentals

 A triaxial cell is outfitted with a soil specimen inside the cell to provide a visual for the students as the three triaxial tests are discussed. The soil specimen is constructed using cement to hold it together since a confining pressure cannot be applied in a classroom environment. With a 3D model in the classroom, this complicated test can more easily be described for each of the three cases (CD, CU, and UU triaxial tests), and the instructor can discuss the function of the plumbing during the consolidation and shear phases of each test.
