Based　on　an　updated　finite　element　(FE)　model　of　the　Xiabaishi　rigid　frame　bridge,　using　the　response　surface　method,　the　criteria　for　verification　of　the　correlation　analysis　testing　were　introduced,　and　the　sources　of　model　and　test　uncertainties　were　analyzed.　Assuming　that　the　random　variables　obey　the　normal　distribution,　the　Monte　Carlo　stochastic　finite　element　(FE)　method　was　employed　to　perform　the　analysis　of　uncertainties.　The　accuracy　of　the　updated　FE　model　was　evaluated,　and　the　FE　model　validation　of　the　continuous　rigid　frame　bridge　with　large　spans　realized.　It　can　be　concluded　that　the　validated　FE　model　of　the　Xiabaishi　bridge　can　reflect　the　current　conditions　of　the　real　bridge,　and　thus　can　be　used　as　the　basis　for　bridge　health　monitoring,　damage　detection　and　safety　evaluation.
