The Influence of Filter Strip Shape on Consolidated Undrained Triaxial Extension Test Results

Source

A series of consolidated undrained triaxial extension tests was performed to investigate the influence of shape of filter strips on the required time of consolidation and undrained shear behavior of clay. Remolded saturated specimens of clay with five different filter strip shapes were consolidated isotropically in the triaxial apparatus and then sheared under undrained extension by decreasing axial stress, while lateral stress was maintained constant. Based on the test results, the filter strip with spiral slit is recommended for practical use in a consolidated undrained extension test because of fast consolidation and low tensile strength.
