成品储存库地基处理桩基布置方案对比

Comparative Analysis of Pile Foundation Layout Scheme for Foundation Treatment of Finished Product Storage

水泥、砂、骨料等建筑材料的生产常采用成品库进行储存,其荷载重、库容大;一般的天然地基难以满足其承载力要求,实践中多采用桩基础。案例中采用盈建科YJK软件对直径为Ф32 m成品库进行建模分析,计算不同桩基布置形式下的桩反力值。结果表明:环形布桩相比于梅花形布桩受力更均匀,相比于正方形布桩可以有效减少桩的根数,具有良好的经济效益。

The production of cement,sand,aggregate and other building materials is often stored in finished product warehouses,which have heavy loads and large storage capacity.It is difficult for ordinary natural foundations to meet their bearing capacity requirements.In practice,pile foundations are often used.The YJK software was used to model theф32m warehouse to calculate the pile reaction value and settlement of different pile foundations.The results show that compared to the plum-shaped pile arrangement,the annular pile arrangement has a more uniform stress distribution,and can effectively reduce the number of piles compared to the square pile arrangement,which has good economic benefits.
