利用短桩控制建筑物沉降设计的探讨

Design exploration of controlling settlement of buildin gs with short piles

对于多层建筑物 ,在地基承载力强度满足设计要求 ,而持力层还较软弱 ,不能满足沉降变形要求时 ,设置刚性短桩复合地基 ,结合褥垫层技术 ,既提高了地基承载力 ,又控制了建筑物的沉降变形。通过设计探讨及施工实践 ,达到了预期的目的。

For multiple?story buildings, when bearing capacit y of ground meets de sign demands, while supporting course is too weak to meet demand of settlement d eformation, if we install rigidity short piles composite ground, combined with t ick course technology, we can not only improve bearing capacity of ground but al so control settlement deformation of buildings. We achieve expected purpose thro ugh design, exploration and constructional practice.
