Abstract

The invention belongs to the technical field of tunnel model simulation experiments, and discloses a tunnel model endoscopic scanning photoelastic instrument, and the instrument comprises an advancingdevice, a rotating device, a photoelastic observation device, a lens adjusting device and an electric control system; the rotating device is fixed on the advancing device, and the photoelastic observation device and the lens adjusting device are fixed on the rotating device; the electric control system is connected with the advancing device, the rotating device, the photoelastic observation device and the lens adjusting device; the photoelastic observation device comprises a polarizer assembly and an analyzer assembly. The polarizer assembly and the analyzer assembly are fixed on the rotatingdevice, and are arranged according to a light path of the reflective photoelastic instrument; and the lens adjusting device is respectively in transmission connection with observation lenses of the polarizer assembly and the analyzer assembly. According to the endoscopic scanning photoelastic instrument for the tunnel model, the photoelastic instrument can be matched with a rock mechanics three-dimensional physical simulation experiment system for observation, high-precision and ideal effect mapping is obtained, and observation operation is simplified.

Description

technical field [0001] The invention relates to the technical field of tunnel model simulation experiments, in particular to a tunnel model endoscopic scanning photoelastic instrument. Background technique [0002] The existing three-dimensional physical simulation experiment system of rock mechanics has imperfect observation means, and the stress-strain response of lining and other structures is not intuitive and accurate enough. In the prior art, there are many discussions on improving the accuracy and reliability of observations by combining photoelastic instruments with rock mechanics three-dimensional physical simulation experiment systems and other instruments. However, the optical properties of photoelastic materials make it impossible to observe the interior of opaque materials such as concrete. The existing reflective photoelasticity instrument is relatively large in size and has a fixed clamping position. Generally, the outer surface of the test piece is fixed for...
