SHEAR DEVICE FOR SHEARING TEST OF SAMPLES OF FINE-GRAINED COHESIVE AND NON-COHESIVE SOIL AND SNOW

摘要

FIELD: testing equipment.SUBSTANCE: shear device is used for shearing test of samples of fine-grained cohesive and non-cohesive soil and snow. The device comprises two vertical holders arranged coaxially. One of the holders is made stationary, and the other - with the possibility of horizontal movement under the action of horizontal shear force loading. In the inner area of the movable holder at least one sectional sample divider of the test body is fixedly located, which is made in the form of a vertical plate located perpendicularly to the direction of action of the horizontal shear force loading. The sample of the test body is placed inside. The presence of sectional soil dividers provides the condition when the shearing force is perceived by the entire the cross-sectional area of the holder, not by its separate part.EFFECT: increase in the accuracy of measuring of shearing mechanical properties of soil.2 dwg
