Composite ground of low energy level dynamic compaction combined with CFG pile treating recent fillingsoil foundation

An example of composite ground of low energy level dynamic compaction combined with CFG pile, which is used in Guizhou mountainous area, is presented to elaborate technology and job practices of the proposed method. In addition, the results of static load test, dynamic penetration test, low strian reflection wave method and settlement observation which will provide creative ideas and experiences for recent fillingsoil work in mountainous area are summarized.
