A Comparison of In-Situ and Laboratory Vane Shear Measurements,
Abstract
In-situ (in place) vane shear measurements and penetration tests were made to depths of 133 cm into the sea floor sediment by use of a vane shear device. These tests were made in the San Diego Trough off San Diego, California, at a water depth of 1,240 meters. The bottom consisted of silty clay material which was uniform throughout the test area. Sediment cores were obtained 60 to 90 cm from five of the six in-situ test sites. Vane shear measurements were made in the laboratory on the core samples at the same depths as the in-situ tests and results compared. Results of the study indicate that the vane shear strengths determined by in-situ tests are consistently higher than the laboratory test values. (Author)
