     A simplified dynamic model of interaction between anchor and rock was proposed, and according to the anchor and soil dynamic model, numerical models were established by ANSYS program. And in order to analyze the effects of changes of anchor parameters （such as elasticity modulus, cross section, length and space ） on anchor slope, by changing anchor parameters, it was studied the effects of anchor parameters on anchor slope seismic per- formances （such as displacement, acceleration and stress）. And analysis results indicate that anchor parameters have different effects on seismic performance of anchor slope, some times they may play bad role in seismic stabili- ty. Increasing cross section of anchor is able to improve seismic stability effectively （maximum decreasing ampli- tude of displacement is up to 33%, maximum decreasing amplitude of acceleration is up to 37.4%, and maximum decreasing amplitude of stress is up to 42.37% ） ; and reducing anchors space is also beneficial for improving seis- mic performance of anchor slope to some extent （maximum decreasing amplitude of displacement is up to 7.53% , and maximum decreasing amplitude of acceleration is up to 9.85 %, and maximum decreasing amplitude of stress is up to 38.3% ） ; increasing elasticity modulus cannot constrain slope deformation effectively,instead increases hori- zontal seismic acceleration of slope （ maximum increasing amplitude is up to 13.8% ） ; while anchor length have lit- tle effect on improve seismic performance of anchor slope. Consequently, suitable anchor parameters should be mod- ified so as to improve seismic performances of anchor slope. And these conclusions may provide some reference for seismic design of anchor slope.
