A triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (e.g. sand, clay) and rock, and other granular materials or powders. Source Typical triaxial tests involve confining a sealed cylindrical soil specimen, with a height-to-diameter ratio of 2:1, … See more The triaxial test is one of the most versatile, comprehensive and widely performed in geotechnical engineering. Table 1, below, lists … See more There are three fundamental triaxial tests that can be conducted in the laboratory, each allowing the soil response for differing engineering applications to be observed: 1. Unconsolidated Undrained test (UU), also called … See more To perform a triaxial test, the system requires a number of components: 1. Load frame: The load frame applies axial deformation to a specimen and can be shared with more than one triaxial cell. In this configuration, … See more Before the test: specimen and system preparation The test specimen must be obtained from a soil sample before being placed into the triaxial cell. For cohesive soils, this may involve … See more WebMay 26, 2024 · In this study, according to ASTM D4767-11 , the UU triaxial test was performed on all specimens following the specific procedures.
