[0033] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0034] like figure 1As shown, a temperature-controllable shear test device for the contact surface between geomembrane and soil includes a rigid base plate 1, and a reaction force frame 2 is fixedly arranged on the rigid base plate, and the rigid base plate located in the reaction force frame is arranged in sequence from bottom to top Set the lower shear box 3 and the upper shear box 5, the two ends of the upper shear box in the shear direction are horizontally constrained on the reaction frame, the upper shear box is filled with soil samples, and the surface of the lower shear box is laid with geomembrane and used. The geomembrane fixture 9 is fixed; the force transmission plate 6 is placed on the surface of the upper shear box soil sample, the normal loading device 19 is set on the top of the force transmission plate, the normal pressure sensor 21 is ...
