Problems solved by technology

At present, the rock samples of the true triaxial test are usually cubes or cuboids, and the test process adopts six-sided loading. The development cost of the overall triaxial testing machine is too high, and only a few units have carried out research and development and purchase.

Abstract

The invention discloses a novel multifunctional test machine for direct shearing and tension-compression loading of rock mass. The novel multifunctional test machine comprises a main body framework, wherein a vertical loading apparatus and a horizontal loading apparatus for loading the rock mass are arranged in the main body framework; the main body framework is provided with a rock sample hoisting apparatus, and one side of the main body framework is provided with a rock sample transporting apparatus; the vertical loading apparatus and the horizontal loading apparatus are respectively independently controlled by a control system and cooperated with each other without interfering each other; the vertical loading apparatus and the horizontal loading apparatus are provided with a load sensor, the load sensor is used for detecting a load force of a loading oil cylinder and connected with the respective control system to form a closed-loop feedback system; and a rock sample is provided with a deformation sensor, the deformation sensor is fixed on the periphery of the rock sample according to the test requirement and used for separately measuring the deformation of the rock sample in the vertical direction and the horizontal direction.

Description

technical field [0001] The invention relates to a novel multifunctional testing machine for direct shearing and tension-compression loading of rock masses. Background technique [0002] At present, the construction of a large number of basic transportation facilities is imminent, and underground engineering is an important part of it. There are many disaster problems in the construction and operation of tunnels and other underground caverns. The collapse of dangerous rocks in tunnels is a common form of disaster, and its occurrence mechanism is mainly manifested in two forms of rock mass compression-shear failure and tension-shear failure. At present, most of the direct shear testing machines on the market are compression shear testing machines, which cannot meet the requirements of rock mass tensile shear testing. Most of the existing tensile-shear test devices have simple structures and single functions, and cannot realize the functions of testing various mechanical prop...
