Method for testing double-sided shearing mechanical property of geocell for railway construction

The invention relates to a railway construction material test, and discloses a railway construction geocell double-sided shearing mechanical property test method, which comprises: placing test samples in a first test box assembly, a second test box assembly and a third test box assembly; the first test box assembly, the second test box assembly and the third test box assembly are sequentially stacked from bottom to top, and a constant load is applied to the second test box assembly in the vertical direction through the third test box assembly; horizontally limiting the first test box assembly and the third test box assembly; applying a horizontal shearing force to the second test box assembly; monitoring the displacement of the upper surface edge and the lower surface edge of the geocell sample in the horizontal shearing force loading process, and calculating the mechanical property of the geocell sample according to the displacement and the horizontal shearing force. According to the method, the double-sided
