%X The spatio-temporal evolution of toppling deformation of an anti-dip bedded rock slope was researched in this article. On the basis of engineering geological survey data, the toppling deformation of bank slope was partitioned into many zones, and then the temporal variations of toppling deformation in different zones were analyzed based on surface displacement monitoring data. Furthermore, inverse distance weighting (IDW) interpolation method was employed to obtain the contours of toppling deformation. Results suggest that 1) the front part of the bank slope is dominated by horizontal deformation and the back part by vertical deformation; the global deformation of slope is controlled by the front part’s deformation; 2) the belt-like deformation area in the middle of   bank slope determines the evolution of global deformation of bank slope, which correspondingly lags behind the deformation in central area. Moreover, the increase in the displacement of central belt-like deformation area would induce the increase in the total displacement of the rear. The belt-like area is considered as collarbone section of the toppling deformation.
