Abstract

The invention provides a double-hydraulic static-pressure supporting type rotatable rock-soil testing machine. The double-hydraulic static-pressure supporting type rotatable rock-soil testing machine is characterized in that a bottom plate and vertical posts are mounted on a base, a lower platform is positioned at a specific height by the bottom plate, the vertical posts and supporting cylinders via through holes at four corners, a ladder-shaped through hole is formed in the center of an upper platform, an upper rotatable table is mounted in the ladder-shaped through hole in the center of the upper platform, a top plate is fixed at the top ends of the vertical posts, a hydraulic servo cylinder is mounted on the lower central surface of the top plate, and a piston rod of the hydraulic servo cylinder is fixedly connected with the upper surface of the upper platform. The double-hydraulic static-pressure supporting type rotatable rock-soil testing machine has the advantages that large-load specimen loading and high-precision rotation can be achieved, so that bulk specimen fracturing tests can be achieved; through high-energy CT (computed tomography) and three-dimensional imaging, rock crack generation and development during fracturing are revealed to be of great significance to rock mechanics progress.

Description

technical field [0001] The invention relates to the technical field of rock and soil testing machines, in particular to a rotatable rock and soil testing machine with dual hydraulic static pressure supports. Background technique [0002] The rock and soil testing machine is a basic scientific test instrument for studying the stress and strain relationship of rock and soil. It is composed of an axial pressure system, a confining pressure system and a temperature control system. The sample force is applied to the sample through the pressure chamber, and at the same time, the upper and lower end surfaces of the sample and the middle of the sample are respectively placed in different temperature environments through the temperature control system, thereby simulating various conditions of the sample at different temperatures. Actual working conditions. However, the traditional geotechnical testing machine is difficult to observe the internal structure of the material, so it is e...
