Compression anchor is a good anchorage structure in the slope and landslide project. Compared with tension anchor, it is a relatively new retaining structure, and the studies on compression anchor under seismic loadings are very limited. To investigate the seismic behavior of compression anchor under earthquake and get it to work much better in an earthquake-prone area, based on the shaking table test, a soil model slope reinforced with compression anchor and frame beam was carried out. In the test, the smooth steel bar and Q235 steel plate ring were used to simulate the anchor tendon and bearing plate of the compression anchor. The testing results indicate that the anchoring slope shows an obvious amplification effect on input seismic waves in both time domain and frequency domain, and the amplification effect of the acceleration response increases along the slope height. The axial force of the compression anchor is relatively uniform along the length of the anchor. As for different anchors in the same column, at 0.05~0.2 g, the axial forces of all anchors show tiny values, and the axial force of the bottom anchor is slightly greater than that of other anchors. The axial force of the bottom anchor is about 2.1~2.8 times that of the other anchors. At 0.3~0.6 g, the axial forces of the upper two anchors and the bottom anchor increase rapidly, while the axial forces of the other two middle anchors increase a little. The axial force ratio of the five rows of anchors from the bottom to the top at 0.3 g, 0.4 g, and 0.6 g is 4.2:1:1:2.1:2.9, 4.2:1:0.9:3.1:3.4, and 3.6:1:0.8:3.2:3.8, respectively. As for different beams, at 0.05~0.2 g, the bending moments of all beams show tiny values, and the bending moment of the bottom beam is slightly greater than that of other four beams. At 0.3~0.6 g, the bending moment of the top beam plays a more and more vital role, while the bending moment of the other four beams shows little variation.
