| 摘 要： | 本文根据三维有限元模型分析探讨了采动区房屋基础滑动层在地表变形影响下的作用,并与现场试验结果进行了比较。分析与试验都表明,在地表拉伸或压缩变形条件下,基础滑动层的设置均能有效地降低墙体和加固构件的采动附加应力,地表水平变形对上部结构的作用存在上限值。

| Abstract: | Effects of slip layer of building foundation subjected to deformations of ground surface in mining areas were studied by 3-D FEM and field test, and results were compared. Bom showed under the condition of ground surface deformation,tension or compression, the presence of foundation slip layer reduces the additional stress effectively,and there is an upper limit for effect of horizontal deformation of ground surface to superstructure limit. |
