Embodiment Construction

[0026] The anchoring interface stress testing device of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0027] Such as figure 1 As shown, the anchorage interface stress testing device of the present invention is composed of a loading system and a loading device; the loading system is a two-way loading hydraulic test system, that is, the loading system consists of a side loading cylinder 9a, a bottom loading cylinder 9b and a hydraulic pressure testing system. The composition of the pump station is not shown in the diagram of the hydraulic pump station;

[0028] The loading device includes a loading frame 12 and a clamping cylinder 5 installed in the loading frame 12 for clamping the anchor force test piece; the loading frame 12 has a bottom frame and side frames; the The clamping cylinder 5 is composed of two symmetrical halves. The clamping cylinder 5 is a cylindrical cylinder with an outer side and an inner circle, an...

Abstract

The invention discloses an anchoring interface stress testing device and a testing method thereof. The anchoring interface stress testing device comprises a loading system and a loading device, wherein the loading system is a bidirectional loading hydraulic testing system and comprises a lateral loading cylinder, a bottom loading cylinder and a hydraulic pump station; and the loading device comprises a loading frame and a clamping column barrel installed in the loading frame and used for clamping an anchor rod force measuring test piece. When the anchor rod interface stress is tested, the anchoring body bears the bottom push load under transverse clamping action through the design of the structure on a testing platform. The testing method not only ensures the transverse constraint force of the anchoring rod, but also realizes the process of transferring force from the base body to the direction of the anchoring body. The process is consistent to the actual stressing condition of the anchoring rod in engineering.

Description

technical field [0001] The invention relates to a test method and a device, in particular to a test method and a device for studying the stress distribution law of the anchor rod interface. Background technique [0002] As a superior rock-soil reinforcement technology, bolting technology is more and more widely used in various engineering fields, but the research on anchoring mechanism still obviously lags behind the development of anchoring technology. In the composite structure composed of anchor rod, bonding material and rock mass, the anchoring interface is a relatively weak part, and many damages often occur at these interfaces, so the test of the stress distribution law of the anchoring interface is very important. Mechanism research, support design and rock mass stability analysis are of guiding significance. [0003] In the existing laboratory tests, the traditional pull-out test is generally used to test the interface stress of the anchor rod. During the test, the ...
