［摘要］南寧吳圩國際機場新航站樓南北總長約330m，東西總長約1 080m，建筑面積18萬m2。航站樓下部主體結(jié)構(gòu)為鋼筋混凝土框架結(jié)構(gòu)；屋頂采用鋼結(jié)構(gòu)，其中中央大廳屋頂為鋼管柱支承的斜交斜放網(wǎng)架結(jié)構(gòu)，指廊區(qū)域屋頂為鋼管柱支承的平面鋼架或平面桁架結(jié)構(gòu)。針對復(fù)雜巖溶地區(qū)的基礎(chǔ)設(shè)計、復(fù)雜曲面屋頂鋼結(jié)構(gòu)、大體量單索幕墻、斜向分叉支承體系等結(jié)構(gòu)特點與難點，介紹了結(jié)構(gòu)相關(guān)問題的處理措施，包括回填復(fù)沖、屋頂設(shè)置溫度縫、構(gòu)件以及屋蓋整體的穩(wěn)定分析、節(jié)點有限元分析等。

［關(guān)鍵詞］航站樓； 樁基礎(chǔ)； 巖溶地區(qū)； 鋼結(jié)構(gòu)屋頂

Abstract: The Nanning Airport construction area is about 180 000 square meters, and it spans 1 080m from east to west and 330m from north to south. Reinforced concrete structure was adopted as low-part structure; the headhouse roof steel structure are cross truss and the pier roof steel structure are plane truss or plane frame, both of them are supported by diagonal branch column. Structural measures are introduced to treat the structural difficulty including foundation in complex Karst area, steel structure of complex surface roof, huge single-layer cable-net curve curtain, diagonal branch support system, which including backfill repeating compacting, temperature expansion joint, stability analysis of steel members and overall roof, FEM analysis of key joints.

Keywords: terminal; pile foundation; complex Karst area; steel structure roof
