White Paper: Dynamic Triaxial Testing

Overview: This three part series has been written to introduce one of the most versatile tests in the geotechnical laboratory – the triaxial test. The papers provide a detailed introduction to the subject of triaxial testing, including the many variations available for assessing soil response across a range of engineering applications. The series is split into the following topics...

  1. Introduction to triaxial testing.
  2. Advanced triaxial testing.
  3. Dynamic triaxial testing. 


This paper presents the dynamic cyclic triaxial testing of soils in the laboratory. It briefly discusses why dynamic tests are required, the soil parameters that may be obtained, the differences between static and dynamic triaxial systems, the general method for conducting a dynamic cyclic test, and a new development relating to dynamic cyclic triaxial apparatuses.
