调沉桩处理复杂地基及上部荷载不均的工程实例

Application of Settlments Adjusted Piles to a Complex Foundation and Uneven Loads of Super-structure

在福州市吉祥大厦的基础设计中 ,通过全面分析场地地基土的特点及主楼的结构特征 ,趋利避害 ,打破常规 ,用少量的桩调平因地基复杂及上部荷载不均匀所造成的超限差异沉降 。

The design of foundation of a tall building is described,which fully analyses the on-site soils characteristics and the structural features of the main building.In the design,the authors make good use of favorable condition and evade unfavorable elements as well as adopt special methods.Only a few balance settlement piles are applied to overcome the excessive differential settlement caused by complex foundation and uneven loads of superstructure.The design results in good effects.
