Abstract
The shear strength of deep-sea core sediments from the northeast equatorial Pacific was measured in various conditions to ensure precision of results. The comparison items were (1) two different measuring systems (hand-held vane and motorized vane), (2) in different places of on-board immediately after collecting the core samples and on-land laboratories after storing these samples for three months in a cold room, (3) two different core samples from a multiple corer within a sampling station, and (4) four different measuring points (holes) from a core sample. In this experiment, the values of shear strength in deep-sea sediments show significant change with depth which increase toward the bottom of core. Also, the results of two cores recovered at the same station indicate that vertical variation of shear strength is mainly caused by the change of physical properties. They strongly support the fact that the difference of vane system and/or experimental conditions are not major factor in the variation of geotechnical properties.
