(廣州珠江外資建筑設(shè)計院，廣州 510095)［提要］建于填海區(qū)的澳門東亞運動會體育館是2005年東亞運動會的主場館，為長軸直徑達(dá)446m的開口橢球體，屋蓋水平投影長軸直徑為328m，短軸直徑224m，呈橢圓形。工程的基礎(chǔ)處理復(fù)雜，屋蓋結(jié)構(gòu)跨度大、體系新穎。介紹了該項目的結(jié)構(gòu)設(shè)計情況和主要的結(jié)構(gòu)分析結(jié)果和重要的技術(shù)措施，著重討論了填海地區(qū)的深基礎(chǔ)、首層超長預(yù)應(yīng)力鋼筋混凝土大板、超大跨度橢球面鋼屋蓋體系及其整體穩(wěn)定等結(jié)構(gòu)設(shè)計中的關(guān)鍵技術(shù)。［關(guān)鍵詞］體育館；大跨度鋼結(jié)構(gòu)；大體積混凝土；負(fù)摩擦力Structural design of Macao Dome for 2005 East Asian GameLiang Yuxing(Guangzhou Pearl River Foreign Investment Architectural Designing Institute, Guangzhou 510095, China)Abstract:As the main site of the 2005 East Asian Game, the Macao Dome is newly built on earth fill seashore. The shape of Macao Dome is an ellipsoid with longitudinal diameter up to 446m and the roof is an ellipse of 328m in longitudinal direction and 224m in transverse direction. The foundation design of the project is complicated, and structure system of the large-span roof is brand-new. The structure design process of Macao Dome is introduced, and important analysis results and technical measures are presented. Key problems such as deep foundation in earth fill seashore, extra long prestressed concrete flat slab on the ground floor, large span ellipsoidal steel roof structure and its overall stability are discussed emphatically.Keywords:gymnasium; large span steel structure; mass concrete; negative friction作者簡介：梁宇行，碩士，高級工程師，英聯(lián)邦結(jié)構(gòu)工程師學(xué)會會員，Email:liang.yuxing@yahoo.com.cn。參考文獻(xiàn)［1］屋宇結(jié)構(gòu)及橋梁結(jié)構(gòu)之安全及荷載規(guī)章(法令第56/96/M號)［S］.［2］鋼筋混凝土及預(yù)應(yīng)力混凝土結(jié)構(gòu)規(guī)章(法令第60/96/M號)［S］.［3］建筑鋼結(jié)構(gòu)規(guī)章(澳門特別行政區(qū)第29/2001行政法規(guī))［S］.［4］地工技術(shù)規(guī)章(法令第47/96/M號)［S］.［5］鋼筋混凝土用熱軋鋼筋標(biāo)準(zhǔn)(法令第64/96/M號)防火安全規(guī)章(RSCI)［S］.
