摘要
The present disclosure relates to the technical field of civil engineering, in particular to a test device for shearing mechanical properties of interface between pile 5 and soil, including a top plate, a support plate and a bottom plate, and a film box is embedded between the support plate and the bottom plate. The film box includes a rubber film cylinder, a bottom supporting board and a cover plate The bottom supporting board is coaxially embedded in the middle of the bottom plate, the bottom supporting board is disposed at the lower end of the rubber film cylinder. The cover 10 plate is used for sealing the upper port of the rubber film cylinder; and the vertical loading device is disposed in the middle portion of the top plate. The vertical loading device is used for applying vertical pressure to the pile. A set of tightening bands are evenly distributed around the outer periphery of the rubber film cylinder, and each tightening band is in arc shape and tangent to the outer circle of the rubber film 15 cylinder. The present disclosure can realize different experimental comparisons, by controlling the displacement stroke of each telescopic rod, when the strokes of the telescopic rods are the same, the same corresponding horizontal pressures are applied to the piles in the respective directions. When the strokes are the different, the different pressures to different sides are realized, which is flexible and adaptable to 20 different experimental requirements. Figure 1
