英文摘要	A large-scale shaking table experiment of loess slope supported by frame anchors with a 1:10 similarity ratio was designed and completed. By loading seismic waves of different types, acceleration peaks and durations, the dynamic response laws of model slope under earthquake action were discussed, and the seismic performance of the supporting structure with frame anchors was evaluated. The test results show that the anti-seismic effect of the supporting structure with frame anchors on the loess slope is significant. Different seismic wave inputs are used to verify its stability in the seismic design of the supporting structure with frame anchors. Under the action of the supporting structure, the loess slope has evident filtering effect on seismic waves and amplification effect on frequency spectrum, and the slope acceleration response has the amplification effect on the near-empty surface and vertical amplification effect. The acceleration response exhibits 'attenuation' phenomenon when the peak earthquake input acceleration is small. Under the support of frame anchors, the displacement of loess slope is effectively restrained, its dynamic earth pressure distribution curve shows 'hyperbolic' change, and the dynamic earth pressure is distributed in an inverted triangle from the foot of the slope to the top along the slope height direction. The test results can provide some reference for the seismic design of the supporting structures with frame anchors of loess slope. © 2019, Science Press. All right reserved.
