Problems solved by technology

However, since the instability of most rock and soil reinforcement structures is caused by large elastic-plastic deformation, the support and reinforcement concept based on the traditional prestressed anchor (cable) system has been unable to adapt to rock and soil (slope rock mass, tunnel surrounding

Abstract

The invention discloses a large deformation tensile force testing system, which is used for testing the large deformation tensile force of an anchor rod or an anchor rope. The system comprises a main rack, a rear chuck component, a front chuck component, a tension device, a measurement and control device, a control module and an analysis module, wherein the rear chuck component is arranged at a first position in the longitudinal direction of the main rack; the front chuck component is movably arranged at a second position in the longitudinal direction of the main rack; the tension device is arranged closely to one end of the main rack and connected with the front chuck component, and tensions a test piece clamped between the two chuck components in a set control way; a sensing module of the measurement and control device senses the displacement of the tension device and real-time tensile force applied to the test piece, generates real-time data, and transmits the real-time data to the analysis module and the control module; the control module controls a test process to be performed according to a set test condition according to the set control way and the input of the sensing module; the analysis module analyzes the input of the sensing module to generate a test result; and an output module outputs the test result. By the large deformation tensile force testing system, static parameters of various anchor rods and anchor ropes can be accurately and effectively obtained.

Description

technical field [0001] The invention relates to a large-deformation tensile testing machine, in particular to a large-deformation tensile testing system for indoor research on the static properties of constant-resistance large-deformation anchors (cables) and other common anchors (cables). Background technique [0002] In recent years, with the rapid development of the national economy, the demand for energy from all walks of life is increasing. my country's open-pit mines have gradually entered the deep mining stage, involving a large number of slopes, active faults, and caverns in the fields of mining, water conservancy, and transportation. Surrounding rock stability issues. [0003] At present, our country is in a period of rapid development of various engineering constructions, and many disasters have also occurred in the process of mining of mineral resources and underground engineering construction: such as rock bursts, rock bursts, landslides and other disasters. For ...
