Abstract

The invention relates to a simulation experiment apparatus used for testing drawing force of an anchor pole and an application method thereof. The experiment apparatus comprises a testing box and a tester. The testing box comprises a box body (13); rock and soil materials (14) placed in the box body, wherein the rock and soil materials are used for testing; the testing anchor pole (18) which is inserted in the center of the rock and soil materials (14); and a contacting slice (15) arranged on the anchor pole (18). The tester comprises a pedestal (11), and a casing (13) arranged on the pedestal (11). One side of the pedestal (11) is provided with a vertical tube (9); a vertical stick is arranged on the vertical tube (9); a first cross bar (2) is arranged on the vertical stick (3), wherein one end of the cross bar (2) in inserted into the top of the vertical stick (3), and the other end is welded with a fixed pulley (23); a cross pipe (7) is arranged at the middle of the vertical stick (3); a second cross bar (16) is inserted in the cross pipe(7); and a dial gauge (19) is arranged on one end of the second cross bar (16). The apparatus possesses following beneficial effects comparing with existing technologies: the apparatus is capable of realizing a complete and realistic simulation of the drawing force mechanism of the anchor pole, providing more accurate and full experiment data for the design of actual anchor pole parameters, and ensuring the safety in practical applications.

Description

technical field [0001] The invention relates to a simulation test device and a test method for simulating the pulling force of a bolt. The test device includes two parts, the test box and the tester, which can realize the complete simulation of the mechanism of the real bolt pullout force; the test adopts the method of loading in stages, which is simple and convenient, and can provide accurate experiments for the design of various parameters of the actual bolt. data and ensure its security in practical applications. Background technique [0002] Due to the rapid development of highway and railway construction in our country, there are many engineering problems in excavating tunnels and slopes in unfavorable geological areas. The anchoring mechanism and its influencing factors of the rock and soil structure in the broken zone still need further research. The analysis of the test data provides a certain reference for the design theory and construction method of bolt reinforc...
