2024 Webinar: Triaxial Lab Testing for Earth Dams

When:  Feb 13, 2024 from 12:00 to 14:00 (ET)
Speaker(s): Ronaldo Luna, PE, PhD, D.GE, Saint Louis University / Luna Consulting, LLC, Professor and Senior Consultant

PDH's: This webinar is eligible for 2 PDH credits.

The triaxial test is the premier laboratory test to evaluate shear strength conditions for earthen embankment dams. This test is common practice in geotechnical engineering but requires a good understanding of the different laboratory steps and procedures. This webinar will present concepts of the triaxial test as it applies to embankment dams. Different stages of a triaxial test such as specimen preparation, saturation, consolidation, and shearing will be discussed in detail. The different types of tests available (UU, CU, CD) for the different loading conditions during the life of an earthen dam will also be discussed. The application of different triaxial tests for different situations will be explained for practical situations in the field.

Key Takeaways: 
Understand the fundamental principles of triaxial testing of soils.
Understand how to use the control of drainage to develop different types of triaxial testing.
Understand how to obtain shear strength parameters for design or rehabilitation of earth dams.
