Embodiment Construction
[0021] The present invention will be further described below.
[0022] A method for making a structural surface model for a direct shear test, comprising the following steps:
[0023] 1) Selection and treatment of structural planes of original rock.
[0024] (1.1) Sampling. Select the undisturbed rock structural plane to be sampled and number it.
[0025] (1.2) Surface treatment. Sand is spread on the ground surface, and the sand surface is generally leveled, and then the undisturbed rock is placed on the leveled sand layer to level the structural surface of the rock mass. Clean the selected original structural surface, and then apply a release agent (oil) on the position to be selected (determined according to the specific size of the structural surface model), and spread an isolation film (polyethylene, with a thickness of 0.02mm).
[0026] 2) Fabrication of structural surface model of footwall.
[0027] (2.1) Place the mold. Place the selected mold (selected according...
