This　paper　proposes　a　construction　deviation　probabilistic　method　that　fits　the　integral　stability　analysis　of　suspend-dome　structure　with　initial　geometrical　defects.　According　to　the　deviation　layout　of　the　construction　site,　the　probabilistic　distribution　of　initial　geometrical　defects　is　introduced,　the　sample　space　is　worked　out　by　computing　the　random　finite　element　model,　and　the　stability　factor　is　gotten　through　analysis　of　these　samples.　With　an　optimized　suspend-dome　structure　model　whose　span　is　93　m,　rise-span　is　1/12,　the　influence　of　initial　geometry　defects　on　the　nonlinear　integral　stability　is　analyzed.　Through　comparison　with　the　result　drawn　from　the　traditional　eigenvalue　buckling　method,　the　nonlinear　integral　stability　factor　drawn　from　construction　deviation　probabilistic　method　is　lower　than　that　of　traditional　eigenvalue　buckling　method　by　about　30%.　With　the　initial　geometrical　defect　taken　into　account,　the　max　value　of　the　initial　geometrical　defects　is　adopted　as　1.645　times　of　the　construction　control　deviation,　and　this　initial　geometrical　defect　is　more　reasonable　and　safe.　The　construction　deviation　probabilistic　method　is　successfully　adopted　in　the　stability　analysis　of　the　badminton　gymnasium　for　2008　Olympic　Games,　and　the　applicability　of　this　method　is　verified.
