摘要
在研制了一个考虑箱形基础与地基及上部结构相互作用的三维空间分析程序ＳＢＳＩＡ的基础上，研究了墙率对箱形基础受力变形及基底反力的影响。研究结果表明：《箱、筏基规范（ＪＧＪ６－９９）》中墙率的规定可以适当降低，对箱形基础受力变形及基底反力的影响不大，但必须注意验算墙体的抗剪强度和基础底板的抗冲切强度。
The effects of the wall-late on the behavior of box foundation and subsoil reaction are studied in the paper using a 3Danalysis program (SBSIA). It considers the interaction of soil-box foundation-superstructure. Some examples are Presented for the illustration.The results are shown that the wall--late for a box foundation specified by the Code (JGJ6-99) can be moderately decreased. The effects on the bent deformation of a box foundation and subsoil reaction are rather slight. However the shear shes of walls and punching shear stress of base plates should be checked in attention.
