  1、主要技術內容
  工具式組合內支撐技術是在混凝土內支撐技術的基礎上發展起來的一種內支撐結構體系,主要利用組合式鋼結構構件截面靈活可變、加工方便、適用性廣的特點,可在各種地質情況和復雜周邊環境下使用。該技術具有施工速度快、支撐形式多樣、計算理論成熟、可拆卸重復利用、節省投資等優點。
  2、技術指標
 ?。?)標準組合件跨度8m,9m,12m等。
 ?。?)豎向構件高度3m,4m,5m等。
 ?。?)受壓桿件的長細比不應大于150,受拉桿件的長細比不應大于200。
 ?。?)構件內力監測數量不少于構件總數量15%。
  3、適用范圍
  適用于周圍建筑物密集,相鄰建筑物基礎埋深較大,施工場地狹小,巖土工程條件復雜或軟弱地基等類型的深大基坑。
  4、已應用典型工程
  北京國貿中心、廣東工商行業務大樓、廣東荔灣廣場、廣東金匯大廈。
