Abstract: Based on analysisof non- linear finite element for embankment and consideratedmertiral sto
chastic, function could begained on Mohr- Columb destroy rule and stochasticvariable of function can
begained by non- linear stochastic finite element, then reliability index of calculating point could be
gained by JC method. Embankment whole stability could be analysed by searching invalidation mode
form reliability index of calculating point. Meanwhile, lowering thevalue of c and tan, soil stable safe
reserve coefficient could be gained, which was compared with the safe coefficient and reliability index
that was obtained by theway of deterministic method.
Keywords: reliability analysis; non- linear; stochastic finite element; high embankment
