| Abstract: | By means of in-situ tests, the engineering features and charateristics of pile-soil stress ratio have been considered after composite foundations of Dry Jet Mixing method piles are loaded, and ways how to get bearing capacity have been suggested. According to deformation and failure of DJM pile, the mechanism of deformation and failure of DJM ground and its method of designing and calculating have been analyzed. |
