Research conclusions: ( 1) It is feasible to analysis the factors of the sliding risk of slope，using analytic hierarchy process combined with expert scoring method． ( 2) In the criterion layer，the influence of technological factors is greater． ( 3) For the technology risk，how to design reasonably and reduce the sliding risk for the slope of embankment is very important． And construction quality only take second place． ( 4) For sliding risk of embankment slope，control the risk of design and construction is the key．
