［提要］ 南山觀音圣像位于三亞南海之濱，為佛教和當(dāng)?shù)芈糜螛I(yè)標(biāo)志性建筑。南山大佛因其建設(shè)場地位于海水環(huán)境中，像體外形復(fù)雜多變，給結(jié)構(gòu)設(shè)計帶來一些不同于普通房屋建筑結(jié)構(gòu)的特點。針對海水環(huán)境對基礎(chǔ)的復(fù)雜影響，通過分析海水對鋼筋混凝土結(jié)構(gòu)的腐蝕成因，設(shè)計中采取恰當(dāng)?shù)乃嗥贩N、低水灰比、厚保護層和環(huán)氧樹脂涂層鋼筋等措施，在海水環(huán)境下保證結(jié)構(gòu)的耐久性。針對不規(guī)則的形體，采用規(guī)則簡單的結(jié)構(gòu)體系——由支撐筒組成的主鋼架，在規(guī)則的主結(jié)構(gòu)體系與不規(guī)則的像體外形間靈活布置次鋼架，以保證傳力途徑的簡捷，體系有序、傳力明確。對主要荷載——風(fēng)荷載取值的分析判斷，既保證結(jié)構(gòu)受力的安全，也考慮到設(shè)計的經(jīng)濟、合理，避免過度設(shè)計。

Order Structure with Complicated Shape—Structure Design of Mt. Nanshan Guanyin/Jiang Wenwei(East China Architectural Design & Research Institute Co.,Ltd., Shanghai 200002,China)
Abstract:Mt. Nanshan Guanyin lies in seaside of the South China Sea in Sanya city, which has been the symbol of Buddhism and local tourism. Due to its specific location with the basement in sea water and complicated statute shape, the design of Mt. Nanshan Guanyin presents different structural characteristics with ordinary building structure. Corresponding to complexity of basement design in seawater, measures of suitable type of cement,low cementwater ratio, thick concrete cover and epoxy resin coated steel bar etc, are adopted in design to guarantee structural durability,by analyzing the causes of concrete corrosion in seawater.Simple order structural system of the main steel frame consisted of braced tube is used in design corresponding to the irregular sculpture shape. Minor steel frames are laid between the main steel frame and sculpture surface to ensure the efficient load transfer. Analysis and judgement of controlling design loadwind load ensure structural safety.
Keywords:main steel frame; minor steel frame; wind load; reinforced concrete structure in seawater
