Problems solved by technology
However, the monitoring cost of this type of method is relatively high, and the installation and operation process is relatively complicated. Due to factors such as high cost and complicated installation and monitoring processes, installing pressure pillows and digital display dynamometers on every part of the roadway surrounding rock not realistic on a single anchor
Therefore, it is difficult for such methods to monitor and judge the load-bearing state of each bolt, and it is impossible to comprehensively understand and recognize the performance of bolt support and the deformation control of the roadway surrounding rock.

Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings.
[0033] like Figure 1 to Figure 5 As shown, the present invention provides a bolt anchoring force monitoring and analysis system based on mechanochromic material, including a circular ring-shaped film 6 made of organic mechanochromic material and a collection and analysis terminal 8; made of organic mechanochromic material When the film is attached to the surface of the object subjected to mechanical force, it is convenient to qualitatively observe or quantitatively detect the color change of the force-bearing part, and then easily match the force, deformation, distortion and damage of the object;
[0034] The number of the annular films 6 is three, and the three annular films 6 are attached to the surface of the spherical cap portion of the tray 7 concentrically from the inside to the outside in turn;
[0035] The collection and analysis terminal 8 includes a casing ...

A system and method for monitoring and analyzing the anchoring force of anchor rods based on mechanochromism. The system includes an annular film made of organic mechanochromic material; three annular films are coaxially attached to the spherical cap of the tray The surface of the shaped part; the collection and analysis terminal includes a casing, a detection light emission module, a color collection module, an analysis processing module and a display module, and the detection light emission module, the color collection module and the analysis processing module are all installed in the inner space of the casing. Method: Lay three rings of circular film on the spherical crown of each tray concentrically, and then apply it on the engineering site; collect the color signal by aligning the hand-held acquisition and analysis terminal with the circular film; analyze and process The module is processed and displayed through the display module; the system integration analysis is carried out. The system and method can effectively and accurately monitor the load-bearing state of each bolt, and can comprehensively understand and recognize the support performance of the bolt and the deformation control of the surrounding rock of the roadway.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering or well roadway support engineering, in particular to a system and method for monitoring and analyzing bolt anchoring force based on mechanochromicity. Background technique [0002] The prestressed bolt support technology has been widely used at home and abroad due to its many advantages, such as effectively controlling the deformation of surrounding rock and effectively reducing the cost of roadway support. When the rock mass in the action range of the bolt is deformed, the working resistance (axial force) value of the bolt will increase to suppress the deformation of the rock mass. Therefore, the real-time working resistance of the bolt reflects the real-time bearing state of the bolt, and also reflects the real-time working resistance of the bolt. The control effect of the bolt on the deformation of the rock mass is obtained. However, due to a variety of factors during on-site...
