How does triaxial shear test work

WebApr 2, 2024 · Triaxial test is a laboratory test used for ascertaining the shear strength parameters of soil specimens placed under confining pressure. The test is performed in two stages. The first stage involves the application of the confining stress and the second stage involves the application of the deviator stress. WebMay 26, 2024 · In this study, according to ASTM D4767-11 , the UU triaxial test was performed on all specimens following the specific procedures. In search of the shear strength of the fiber-reinforced FAS specimens, confining pressures of 200, 300, and 400 kPa were chosen . Then, the application of a strain rate of 1.5 mm/min was carried out on …
