[摘要] 依據(jù)《建筑樁基技術規(guī)范》(JGJ94—2008)提出的以減小差異沉降和承臺內力為目標的變剛度調平設計,針對傳統(tǒng)均布CFG樁基處理進行平面布置優(yōu)化并應用于工程實例,從而合理考慮樁土的共同承載能力,減少沉降差異,降低筏板內力及配筋,望能為類似工程地基設計提供參考。

Abstract : Based on Technical code for building pile foundations(JGJ94—2008) to reduce differential settlement and internal forces for variable rigidity design, CFG piles with traditional uniformly distributed layout to were optimized and applied toengineering examples, so jointly bearing capacity of piles and soil was reasonably considered, overcome and reduce the differential settlement, reduce internal forces and raft's reinforcement, which can provide a reference for similar project’s composite foundation design.
Keywords : ground treatment; composite foundation; variable rigidity design
