Abstract：In order to identify the spatial location of the critical blocks in rock slopes，a theory which describes the interaction among the rock blocks by cross-impact analysis was put forward. The method of predicting the uncoordinated deformation regions，distinguishing the critical blocks，evaluating the reinforcement effects was introduced as an example in the feedback analysis of Dagangshan slope. Compared with the traditional time series analysis，the cross-impact analysis requires less incremental displacement information and achieves the spatial distribution of critical block efficiently.
