Different　landslide　analysis　methods　were　compared　in　this　paper,　and　the　analysis　method　of　levee　project　seismic　landslide　risk　probability　was　established　based　on　Morgenstern-Price　and　Monte　Carlo　methods,　and　then　the　landslide　risk　assessment　standards　were　developed.　The　result　shows　that　liquefaction　can　lead　soil　layer　strength　reduction,　and　will　trigger　and　accelerate　landslide,　therefore,　the　impact　of　soil　liquefaction　must　be　reasonably　considered　in　levee　and　dam　seismic　stability　analysis.　©　(2011)　Trans　Tech　Publications,　Switzerland.
