The structural system selection method of the overall system and sub-systems of the convention center were introduced. The bonded prestressed technique is adopted for cantilever beams and floor beams with large span and heavy loading, while the unbonded prestressed technique is adopted for the tension section of cantilevered stairs. Finite element method was used to analyze the comfort levels of large cantilevered stands, large span floors and spiral stairs. The combined pile-anchor foundation was used to avoid the overturning moment of exterior columns due to the interlayer effect.Keywords: Hainan International Convention and Exhibition Center; structural system selection; comfort level; prestress; alien stairs; combined pile-anchor foundation作者簡介：王載，碩士，教授級高級工程師， Email：wangz@cadg.cn。參考文獻(xiàn)［1］王文宇，王載.江西藝術(shù)中心歌劇院結(jié)構(gòu)選型分析［C］//第二十一屆全國高層建筑結(jié)構(gòu)學(xué)術(shù)交流會論文集.南京：2010.［2］王載，任慶英，張曉宇.金鼎大廈結(jié)構(gòu)設(shè)計(jì)中方案的比較及優(yōu)化［J］.建筑結(jié)構(gòu)，2006,36（5）：41-44.
