In addition, since the density of the sandstone 200 is very important in the experiment, the minimum density, the relative density, and the maximum density can be accurately measured and input to the sandstone filling unit 150.

The density of the sandstone 200 is measured before the experiment, and the density must be measured even after the experiment.

In addition, since the volume varies depending on the shape of the intercell 100, it is necessary to accurately measure and input density.

In addition, white cement or wheat flour may be applied to the upper end of the sandstone 200 injected into the sandstone filling unit 150.

The white cement or wheat flour is used to measure the qualitative shear strain of the intercell 100 under external force.

The actuator is a device that applies an external force to one surface of the intercell 100.

In addition, the actuator is a representation of the power of the blue wave received by the intercell 100 in the actual field, and is measured and executed.

The displacement meter 500 measures displacement of the intercell 100 in a direction of a load, that is, a direction of a force received from the outside and a direction perpendicular to a load direction, that is, a direction of a direction of a force received from the outside.

Thus, the displacement meter 500 is composed of a first displacement gauge (not shown) and a second displacement gauge (not shown).

The first displacement gauge is installed on the other surface facing the one surface of the intercell 100 that receives the external force of the actuator.

In addition, the second displacement gauge is installed on a side surface between the one surface and the other surface.

Therefore, the first displacement gauge measures displacement in the load direction of the intercell, and the second intercell measures displacement in the direction perpendicular to the load direction of the intercell.

In the present invention, the displacement meter 500 uses the linear variable differential transformer (LVDT).

The LVDT refers to a form of an electrical transducer that measures a linear distance difference. Three solenoid coils are positioned around the tube.

The center coil is the main and the other two are located outside, and the cylinder-shaped magnetic core moves along the center of the tube to inform the position value of the measurement object.

This is also possible, and thus the present invention does not exclude that the order of the shear load cell attaching process (S13), displacement gauge attaching process (S14), and friction damping member attaching process (S15) is adjusted according to the field situation.

The external force action step (S20) is a step of causing the shear of the intercell 100 by applying an external force by the actuator to the intercell 100.

The actuator may act on one surface of either the first intercell 110 or the second intercell 120 among the intercells 100.
