中文摘要 | 本文檢討位於高雄市苓雅區東帝士國際廣場大樓(T & C Tower),地上85層地下5 層之超高大樓基礎之規劃,設計至施工之考量過程與儀器監測結果。該大樓採用均勻對稱三 管式結構,基礎則基於地層特性、施工技術、鄰房狀況與施工工法之考量而採用框格式地下 連續壁牆,監測結果顯示大樓平均沉陷相當均勻在中央區約 5-6 公分,四周約 3-5 公分, 地下水壓於營造至約 35 樓停止降水後,隨樓層之增高逐漸回升,於完成時回升至原地下水 壓狀態。 |
英文摘要 | This paper describes the process of design and construction and monitoring results of the foundation system for T & C Tower, an 85-storey highrise building with 5 levels of basements in kaoshiung, southern Taiwan. The structure system design is a triple tube in series with 8 mega columns each to support loads up to 40,000 metric tons; Considering the soil conditions, construction techniques available at the time, safety of vicinity buildings and method of construction, a grid pattern of slurry walls underneath the floating raft foundation system was used. Monitoring results indicate that after completion of 85 stories, the settlements at the central portion and periphery of the building are 5-6cm and 4-5cm, respectively; while the ground water pressure at the bottom of the raft after stopping dewatering when construction reached 35F, it increased gradually towards its natural level as construction progressed towards 85F. |
