[摘要]《建筑地基處理技術規(guī)范》(JGJ 79—2012)中的“復合地基靜載荷試驗要點”有如下條文:當壓力-沉降曲線是平緩的光滑曲線時,可按相對變形值確定,…,對有經驗的地區(qū),可按當地經驗確定相對變形值。然而,按當地經驗確定相對變形值的具體過程和步驟如何,規(guī)范卻沒有做進一步的闡述。為此,針對這一問題,結合在柳州某項目積累的一些CFG樁地基處理工程經驗,進行總結分析,以供探討。

Abstract: The composite foundation static load test of Technical code for ground treatment of buildings (JGJ 79—2012) introduces that when pressure-settlement curve is gentle and smooth, relative deformation can be used; relative deformation can also be derived from the local experiences. However, how to work out is no elaborated in the code. Therefore, this problem was summarized and analyzed for discussion on the basis of the experience about CFG pile in Liuzhou.
Keywords: CFG pile; composite foundation; static load test; local experience; relative deformation
