Diverse　risk　events　and　risk　possibilities　are　involved　in　the　design,　construction　and　maintenance　of　highway　cut　slopes　because　slope　risk　and　elements　at　risk　are　varying　during　these　period.　It　is　therefore　necessary　to　conduct　differentiated　risk　assessment　and　life　cycle　risk　control.　In　this　paper,　a　technical　framework　is　proposed　for　life-cycle　risk　analysis,　assessment　and　management　of　highway　cut　slopes　based　on　a　modified　Hall　three-dimensional　morphology　of　systems　engineering.　Critical　points　of　risk　zonation,　data　collection　and　information　cataloging　during　risk　analysis　in　a　typical　design,　construction　and　maintenance　life　cycle　are　clarified.　Distinct　definitions　and　analysis　methods　of　failure　probability　in　the　process　of　hazard　analysis　are　subsequently　elucidated.　Meanwhile,　the　definitions　and　measures　to　recognize　hazard-affected　targets　and　to　evaluate　their　damage　and　space-time　probability　as　well　as　vulnerability　and　other　essential　indices　are　determined　in　the　process　of　hazard　consequence　analysis.　The　applicable　methods　for　qualitative　and　quantitative　risk　estimation　in　different　stages　of　slope　engineering　are　also　revealed.　Technical　procedures　and　key　implementation　points　in　each　aspect　such　as　slope　risk　assessment　and　benefits　evaluation,　comparison-and-　selection　and　planning　of　solutions　and　countermeasures　for　risk　regulation,　monitoring,　verification　and　modification　are　further　discussed,　respectively.　Principles　of　determination　of　risk　tolerance　standard,　ideas　to　enhance　the　accuracy　and　reliability　of　risk　assessment　are　finally　proposed.　Research　findings　of　this　paper　preliminarily　standardized　the　procedures　and　technical　program　for　risk　assessment　and　management　of　highway　cut　slopes　during　their　life　cycles.　It　is　hoped　that　this　paper　will　bring　forth　new　ideas　and　gradually　develop　and　perfect　the　framework　in　practice.　©　2017,　Science　Press.　All　right　reserved.
