A Comparison of the Test Results of Vane and Direct Shear Tests Made on Recent Marine Sediments

摘要

Shear strength envelopes calculated from consolidated-undrained direct shear tests (hereafter called direct-shear lines) were compared to strength envelopes calculated from vane shear tests (hereafter called vane-shear lines) made throughout the length of a sediment core. These comparisons were made on shear strength measurements from seven recent marine sediment cores. The seven sediment cores used for this study were obtained from the upper San Diego Trough slope in water depths of 249 to 291 meters by Lockheed's submersible DEEP QUEST. The materials tested were classified primarily in the clayey silt to silty clay range based upon grain size distribution. (Author)
