摘　　要：考虑桩锚土的相互作用 ,结合实例研究深基坑桩锚支护结构受力和变形特性。研究结果表明 ,土锚的位置、支护桩的刚度、被动区土的“m”值对桩锚支护结构受力和变形特性均有较大的影响 。The force and deformation properties of pile-anchor support structure in deep pits are studied considering pile-anchor-soil interaction. The study results show that there are great influences of the location of soil anchor, the stiffness of support pile, and the 'm' value of the subsoil at positive area on pile-anchor support structure, and the soil anchor plays key role to support deep pits.
