自重湿陷性黄土地区桩基设计探讨
|
摘要
根据自重湿陷性黄土的特点、《湿陷性黄土地区建筑规范》(GB 50025-2004)和《建筑桩基技术规范)(JGJ 94-94)中关于桩基设计的对比分析,通过自重湿陷性黄土场地工程实例分析计算,依据负摩擦产生的机理——中性点理论,论述了自重湿陷性黄土场地中桩基设计应考虑中性点,而不应全部计入负摩阻的观点。
Because of the characteristics of damping collapse loess under dead weight,by the comparative analysis on pile construction design in Construction Standards of Damping Collapse Loess Area(GB 50025-2004)and Technical Regula- tion of Construction Pile Foundation(JGJ 94-94),Based on analytical calculation on the field case and according to nega- tive friction mechanism-nutral point theory,it is expounded that for pile construction design in damping collapse loess un- der dead weight,neutral point should be taken into consideration and negative friction not be substitute in total.
