In the actual project，the evaluation of slope stability is still based on single plate thickness calculation formula． In fact，slope
stability is affected by many factors such as board length，structural type and environmental conditions． How to sort the influence factors is the
key problem in the design of slope protection． On the basis of the calculation formula for the anti-sliding safety coefficient of concrete slope
protection，the sensitivity analysis of slope stability is performed by using the orthogonal design，five factors including the length of slab，
thickness of slab，wind speed，slope ratio and cushion material are considered． And the analytical conclusion is used to solve a slope collapse
problem of actual projects． The results show that the length of slab has the most sensitive effect on the stability of slope，followed by the wind
speed and slope ratio，while the influences of thickness of the slab and cushion materials are insignificant． The research results serve as a
reference for the slope design，stability evaluation and reinforcement of the existing projects．
