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.

In the practice we have no special design of the approach slap , and the theoretical thereunder is not so reasonable. For example, when calculate the length of the approach slap, we adopt the permission differential change slap and settlement, without considering the height of road embankment filling , the form of abutment and the properties of the filling sort, so sometimes it is hard to eliminate the bridge head bump completely because of the disjoint, rupture or overshort of the approach slap, influencing the use of the road and bridge.

实践中一般桥头搭板不作专项设计，且理论依据不甚合理，如搭板长度计算采用桥头容许变坡差和沉降量确定，没有考虑路堤填土高度、桥台形式及填土性质，所以有时会出现搭板脱空、断裂或过短而未能彻底消除跳车现象，从而给道路桥梁的使用带来影响。
