Aiming at slope types, features, deformation traits and destroy mechanism of high steep valley slope at Jinping Ⅰ Hydropower Station, and applying monitoring results, a comprehensive prediction design is suggested. In the space, according to the occurrences of unfavorable geological phenomena such as faults F5, f(subscript 42-9) deep fracture SL(subscript 44-1) and lamprophyre vein X, all of them can be treated as the boundary conditions for slides, potential instable blocks of slope on the left abutment are estimated which take on a wedge-shaped sliding model. In the sametime, through using three kinds of joint prediction methods such as statistic models and nonlinear models, judging from the shape of curves of deformation-time and their deformation velocities, it is found that the slope is at the state of slowly creeping to uniform deforming with a deforming velocity of 0.05 mm/d.
