At present,there are already a lot of fruits in research on stability of consequent rock slope.By far,the analysis model and the analysis method both aim at this type of slope.But the reverse slope which typical structure characteristic is the strata bedding surface and slope strike the same but the opposite tendency,at the same time if there are one or more positive slope direction joints which will cut rock layer to discrete blocks,it is more prone to tilting failure which is different from anciently.For such antidip layered rock slope,the system study of its failure mode and mechanical have never be reported up to today.Therefore,this paper use a large geotechnical engineering simulation analysis system FINAL which introduce from Austria as a platform,establish several typical antidip layered rock slope model.Through special discrete finite element model and test of numerical value,the slope tilting failure mechanical and mode are studied,and directly provide reference to engineering design.
