Abs tract: Seism ic liquefaction problems of embankment slope related to two different subject fields ( geotechnical
engineering and engineering seismology), is a cross topic of slope engineering and sand liquefaction. Sand soil un
der embankment slope can be liquefied by earthquake, and can lead to liquefaction problems such as bearing ca
pacity, settlement, lateral spreading, sand boils and global sliding. U singNCCER method ( SPT), Mononobe Ok
abemethod, Koernermethod and Felleniusmethod, the assessment index system including liquefaction safety fac
tor, liquefaction lateral spreading safety factor, liquefaction sand boils safety factor and sliding safety factor, is put
forward to evaluate the security of embankment slope w ith liquefaction problems. A s a ca
