Problems solved by technology

[0004] The force on the bolt on site is caused by the deformation of the rock mass, that is, the deformation of the surrounding rock drives the deformation of the bolt to generate resistance, so there are anchoring sections and pull-out sections in the anchorage length, and the existing indoor pull-out test is to pull the bolt deformation, so It can only study the performance of the anchorage section, which is inconsistent with the stress state of the anchor rod in the actual project, and cannot effectively reflect the stress state of the real anchor rod, so it cannot measure the force of the pallet that is consistent with the actual stress state

Abstract

The invention discloses a test method and device for force analysis of a drawing process, and relates to the technical field of anchoring system test. The test method for force analysis of the drawingprocess provided by the invention comprises the following steps of: mounting a sensor and a prepared sample, wherein the sample comprises a rock sample, an anchor rod, a tray and an anchoring agent;applying an axial load to the sample; and recording the side deformation and the force of the tray. The invention also provides a test device for analyzing the force of the drawing process with the test method for performing force analysis of the drawing process. According to the test method and device for force analysis of the drawing process, the force state of the anchor rod and the tray in thedrawing process can be accurately tested and analyzed, the real force of the anchor rod and the tray is reflected, and the anchoring system can be designed conveniently.

Description

technical field [0001] The invention relates to the technical field of anchoring system tests, in particular to a test method and device for stress analysis in a drawing process. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are set forth in the claims and detailed description. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Bolt support is the most commonly used measure in the field of rock and soil reinforcement. The anchoring system consists of surrounding rock, anchor rod, anchoring agent, tray, and lock nut. The performance of the entire anchoring system is controlled by the weakest part of each component. Anchor failure occurs at the pallet. At present, there are few experimental studies involving the stress state of the pallet, and corresponding research methods are lacking. [0004] The force on the bolt on site is caused by the defo...
