摘要
台北國際金融中心之101F超高大樓基礎設計採用深入平均達20公尺之軟弱、年青桂竹林層岩盤中之反循環基樁,本文介紹其規劃、設計與載重試驗之過程、下壓及拉拔荷重分別高達4060T及2200T之載重試驗結果之分析以獲得試驗樁之極限承載力、各地層之T-Z特性曲線及利用試驗樁之施工過程與試樁結果分析以改進反循環工程樁施工規範及使用於工程樁之行為設計。
英文摘要
Reverse circulation piles (RCP), installed averagely 20m into the young, soft to weak Ku-chu-lin formation bedrock, were used in the foundation design to support the 101-storey Taipei International Financial Center. This paper describes the process of foundation planning, design and pile load tests, the evaluation of ultimate bearing capacities and T-Z charateristics of each bearing stratum from pile load tests data, with downward and pull-out loads up to 4060T and 2200T, respectively, and the utilization of these results to modify the RCP installation specification and the performance design of the foundation piles.
