Sensitivity similar material and preparation method thereof

The invention relates to a sensitivity similar material and a preparation method thereof. In the method, Vaseline, paraffin, conductive carbon black, powdered rubber and short carbon fiber are adopted as raw materials in a mass proportion; and the method comprises the following steps of: heating and melting the Vaseline and the paraffin, stirring, respectively adding the conductive carbon black, the powdered rubber and the short carbon fiber, and uniformly mixing. The similar material has sensitivity, can directly acquire deformation information of a model test through macroscopic resistance testing without an extra test instrument so as to greatly facilitate the testing in an test, can be used for simulating a geotechnical similar material, has lower strength, can complete the test under smaller pressurizing load along with simple pressurizing equipment, and has the advantages of wide sources of the raw materials, easy processing without maintenance, capacity of being recycled, and great reduction of testing
