强夯法处理深厚杂填土及湿陷性黄土地基实例分析

Case Analysis on Deep and Thick Miscellaneous Fill and Collapsible Loess Foundation Treated by Dynamic Compaction Method

为减少深厚杂填土及湿陷性黄土地基的沉降量,提高地基承载力,采用强夯法对太原酒厂搬迁工程生产厂区地基进行加固处理,地基处理结束后进行钻探取样、载荷试验、静力触探和动力触探试验,处理后的地基承载力特征值大于200 kPa,压缩模量大于30 MPa,证明强夯法处理该地基满足设计要求。

In order to reduce the settlement of deep miscellaneous fill and collapsible loess foundation and improve the bearing capacity of the foundation,the dynamic compaction method is used to reinforce the foundation of the production plant area of the relocation project of Taiyuan distillery.After the completion of the foundation treatment,according to the drilling sampling,load test,static penetration test and dynamic touch test,the characteristic value of the bearing capacity of the foundation after treatment is greater than 200 kPa,and the compression modulus is greater than 30 MPa,which proves that the dynamic compaction method meets the design requirements of the foundation.
