Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] refer to Figure 1 to Figure 10 , a multi-scale rock direct shear instrument, which can measure rock samples in a certain tonnage range and a certain size range. The rock direct shear instrument is mainly composed of a vertical loading mechanism 1, a loading moving mechanism 2, a lateral load supporting mechanism 3, and a shear loading mechanism 4. It is composed of sample height adjustment mechanism 5, lower sample restraint mechanism 6, frame 7, hydraulic system and measurement and control system. The frame is composed of a base beam, a left beam, a right beam and an upper beam, and the beams can be fixed by bolts and welding.

[0029] The vertical loading mechanism 1 is connected to the upper end of the loading and moving mechanism 2, the two sides of the loading and moving mechanism 2 are respectively connected to the lateral load supporting mechanism 3, an...

Abstract

The invention provides a multi-scale rock direct shear apparatus. The multi-scale rock direct shear apparatus comprises a framework, a vertical loading mechanism, a loading and moving mechanism, a transverse load supporting mechanism, a shearing and loading mechanism, a test sample height adjusting mechanism and a lower test sample restraining mechanism, wherein the vertical loading mechanism is connected with the upper end of the loading and moving mechanism; the two sides of the loading and moving mechanism are respectively connected with the transverse load supporting mechanism; the test sample height adjusting mechanism is located below the loading and moving mechanism, and a detection station for placing a test sample to be detected is arranged between the test sample height adjusting mechanism and the loading and moving mechanism; the lower test sample restraining mechanism is connected below the test sample height adjusting mechanism; the side edge of the detection station is provided with the shearing and loading mechanism; the vertical loading mechanism is mounted at the upper part of the framework; the transverse load supporting mechanism is mounted at the upper middle part of the framework; the shearing and loading mechanism is mounted at the lower middle part of the framework; the lower test sample restraining mechanism is mounted at the lower part of the framework. The invention provides the multi-scale rock direct shear apparatus which effectively meets a large-span load and the testing of the size of the test sample, and has good reliability.

Description

technical field [0001] The invention relates to a direct shear instrument. Background technique [0002] At present, the methods for determining the shear strength of rock structural planes at home and abroad mainly include direct shear test method, indoor model test method and empirical estimation method. The method of comprehensively obtaining the shear strength of structural planes through direct shear tests combined with engineering geological survey data is commonly used by rock mechanics workers in China. From the data retrieval, there are many direct shear equipment at home and abroad: such as the LG-140 large-scale high-performance contact surface direct shear produced by Durham Geo in the United States, the large direct shear produced by ELE in the United Kingdom, and the servo servo produced by GCTS in the United States. Controlled direct shear test system, TH-20t large-scale soil-structure contact surface cyclic loading shear instrument developed by Tsinghua Univ...
