Fixed cubic measure, constant pressure power combined use ring shear test device

摘要

PURPOSE: To correctly measure residual strength exhibited on a slide fade by reproducing landslide and slide of slope failure with a simple structure. ;CONSTITUTION: A lift 15 which is vertically moved by a jack 18 is mounted on two support pillars 2,2 supported by a base 1 and an upper end plate 33, while a shearing shaft 7 which is rotated by a servo motor 14 is pivoted on the lift 15 via a torque meter 8. A movable plate 25 which can be positioned at optional positions of the pillars 2, 2 above the lift 15, while a lower sample container and an upper sample vessel are placed in a water tank 20 attached to the shearing shaft 7 and on an opposite face with the movable plate 25, respectively. Then upper ends of pressure applying levers 28, 28 exhibited in the upper sample vessel through the movable plate 25 are connected to an output end of a load mount part B placed on the upper end plate 33 via an appropriate load cell 32.;COPYRIGHT: (C)1993,JPO&Japio
