Strength change feature of surrounding soil in the vicinity of DJM columns in ground improved by DJM-PVD combined method

More Information
  • A remarkable combined method of the dry jet mixing with prefabricated vertical drains (DJM-PVD combined method) is innovated and successfully practiced in a highway project on very soft clay in Jiangsu Province,China. The strength change feature of surrounding soil in the vicinity of a DJM column is investigated. The field results of cone penetration and vane shear tests indicated that the strength of surrounding soil decreases in a short period after the installation of DJM due to the destructi...
