Method for visualizing soil layer anchoring body stress transmission mechanism test

The invention discloses a method for visualizing a soil layer anchoring body stress transmission mechanism test. The method comprises steps of manufacturing an anchoring body test piece and assemblinga test device and carrying out a pull-out test. The method is characterized in that the anchoring body test piece is an anchoring body test piece with a semicircular section and is manufactured in amold cylinder, an anchoring body test piece is placed in a semicircular barrel of a glass cover plate to be manufactured into a test device, the test device is installed on a tension tester, a high-speed camera is aligned to the glass cover plate, the tension tester is started to apply tension, and microscopic and macroscopic deformation and strain states are recorded through shooting of the high-speed camera. A group of corresponding deformation data is obtained through drawing tests of anchoring body test pieces with different roughness, different sand shapes and different lime-sand ratios and different soil samples,
