Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] refer to Figure 1 ~ Figure 4 , a stepless adjustable shear box assembly method suitable for regular structural surfaces with equal height and arbitrary plane size, including the following steps:

[0034] 1) Select the sample size of the test structural surface: select the corresponding structural surface sample according to the experimental design plan.

[0035] 2) Assemble the lower shear box 2: place the lower shear box base 201 on the shear box holding platform of the direct shear tester, and insert the four lower shear box stepless supports 4 into the lower shear box respectively The No. 1 guide groove 202 and the No. 2 guide groove 203 of the lower shear box slide to the maximum size of the lower shear box 2, so as to press and release the sample B on the structural surface of the lower plate.

[0036] 3) Place the lower wall structure sample B: place th...

Abstract

The invention provides an assembly method suitable for a stepless adjustable shear box with regular structural surfaces having equal altitudes and arbitrary plane sizes. The method comprises the following steps: 1) selecting a tested structural surface sample size; 2) assembling a lower plate shear box; 3) putting a lower plate structural surface sample at the middle part of the shear box; 4) fixing a lower shear box stepless support; 5) putting an upper plate structural surface sample on the lower plate structural surface sample in a matched mode; 6) assembling an upper plate shear box; 7) fixing an upper shear box stepless support; 8) performing a direct shear test; 9) disassembling the shear box; and 10) performing the subsequent tests according to the steps 1)-9). The method provided by the invention has the advantages of good testing effect, convenient operation, short construction period, low manufacturing cost and small space occupation.

Description

technical field [0001] The invention relates to a stepless adjustable shear box assembly method suitable for regular structural surfaces with equal heights and arbitrary plane sizes, suitable for direct shear tests on structural surfaces of arbitrary regular sizes within the maximum testable size range, and belongs to engineering technology field. Background technique [0002] In human engineering activities, engineering accidents caused by rock mass deformation and instability emerge in endlessly, causing huge loss of life and property. The study of the size effect of rock discontinuities is of great significance to guide the stability of rock mass engineering. To conduct direct shear tests on rock discontinuities of a series of sizes, a shear box of the corresponding size is required. The usual practice is that each A rock structural surface sample of different sizes requires a shear box matching the size of the sample. This method not only requires a large number of shea...
