To study the resistance-reducing effect of bionic surface on cone of screw pile for preventing flood and rushing to deal with an emergency, a number of bionic surface plates were designed based on the unsmoothed surface morphology of compound eye of ant, a typical soil animal. By using of scanning electron microscopy technology, it was found that the compound eye of ant was made of a lot of small convex eyes. These small convex eyes were arranged in dense style. On the surface of compound eye of ant, there were waveform characteristics. The cross section of compound eye was waveform curve which had continuous periods and amplitudes. Based on these characteristics, experiments of trolley were designed, including an orthogonal experiment for bionic surface plate and the contrast between bionic surface plate and smoothed plate. The results of trolley experiments showed that within the experimental factors and levels, the vertical loads on bionic surface plate and convex diameter produced greater effect of resistance-reducing.
