纠倾工程中控制地基附加沉降变形的若干问题

Problems on Controlling Additional Settlement of Foundation in Correcting Tilt Project

针对多层砌体结构纠倾工程,利用有限元程序,对水平钻孔纠倾中地基附加沉降变形的影响因子进行了研究分析。得到土的物理性质(干密度和含水量)、上部结构刚度差异对砌体结构墙下条形基础下地基附加沉降变形产生重要影响的规律性结论。

Taking inclination rectification project for an multi-storey masonry structure as an example,the authors study influence factors of additional basement settlement by finite element method during inclination rectification with horizontal holing,and draw some conclusions on the important effect of physical factors of soil and different rigidity of upper structure on additional basement settlement under strip foundation of wall of a masonry building.
