[Objective] As a kind of slope disaster

the threat degree of sand-sliding slope has been increasing in recent years due to the influence of human activities. The stability of the sand-sliding slope around Lhasa City was studied in order to provide bases for the early warning and treatment of the sand-sliding slope.[Methods] By selecting the relatively typical sand-sliding disaster around Lhasa City

the paper analyzed the influence of ten factors

such as slope height

rock mass structure and annual average rainfall

on the stability of the sand-sliding slope by using analytic hierarchy process and fuzzy comprehensive evaluation.[Results] The sand-sliding slope formed by weathering-dominated rock mass was relatively high in risk level

and the whole was scattered and sandy

which was easy to spread. The sand-sliding slope formed by landslides along the road was generally low in risk level

with large debris particles and steep slope potential.[Conclusion] At present

the development trend of the unstable sand-sliding slope disaster in the area around Lhasa City is not optimistic

which should be paid more attention for relevant administrative agencies. The evaluation method in this paper is reliable

which can accurately and rapidly evaluate the stability of sand-sliding slope.
