Abstract:In order to study the dynamic response of homogeneous soil slope supported by anchors and lattices under seismiv loading

based on the shaking table test

the mechanism behavior of anchor bars under earthquake

and the difference of dynamic response of anchor bars at different heights were analyzed

and the deformation and failure machanisms of homogeneous soil slope and its supporting structures under seismic load were discussed. Experimental results showed

under dynamic loading

the dynamic strain of anchor was hypersensitive to low-frequency and high magnitude of acceleration of earthquake wave; acceleration magnitude changed from low to medium to high

the position of the bolt to bear larger load also changed in anchored slope

the corresponding order was from middle to top to middle; if the earthquake intensity was large enough

the middle anchor would be damaged firstly

followed by the bottom bolt. The traditional design idea “strenthening slope waist and fixing slope toe” should be used when an anti-seismic anchorage system is designed to make a slope stable. In addition

strengthening the anchor heads of top-row anchors and the upper slope face is a good method to protect the slope from being influenced by the seismic superficial effect. The difference of slope dynamic response should been fully considered under small or big earthquake. The results provided a reasonable foundation for the design of the anchor bars supporting under earthquake．
