Based on the unloading rock mass theory, the primary situation, excavation situation, unloading situation, reinforcement situation, sluice situation and creeping situation were considered. On the basis of the stress analysis and deformation analysis, the deformation theory and the stability of rock mass of the high slopes of Geheyan Power Station under the condition of several factors were studied. And then the function on distortion of the slopes were found. Compared with the monitoring results, the validity of analysis was proved, and further deformation of the high slopes was predicted. Meanwhile, some suggestions for the monitoring disposal based on the analytical results were given. Key words: three-dimensional model; unloading rock mass theory; deformation mechanism
