英文摘要	Loess is a type of porous, weakly cemented sediment. Due to the unique dynamic characteristics of its structure, loess exhibits high seismic vulnerability. Studying the dynamic response of a loess slope supported by frame anchors under earthquake can facilitate the effective seismic design of permanent flexible retaining structures in loess areas. In this paper, the model of a loess slope supported by frame anchors was established by the finite element software PLAXIS 3D, and the results of numerical simulation were verified by a shaking table test. Considering the characteristics of the loess, the dynamic response of the loess slope under earthquake was analysed. The results show that the most dangerous section of the loess slope supported by frame anchors is on the upper part of the slope under the action of earthquake, and the acceleration response of the slope has "amplification effect", "delay effect", and "attenuation effect". The numerical simulation results are in good agreement with the shaking table test results, which can be used as a basis for seismic design of frame anchors in loess areas. © 2020, Taiwan Geotechnical Society.
