잭파일을 활용한 건축물의 지하 및 지상증축에 관한 연구

A study on Underground and Above-ground Extensions of Buildings using Jack-piles

There are many demands for vertical extension construction method in domestic large cities. In this paper, we analyzed and presented the results of examining the cases of ground floor extension and basement extension using the jack pile method. Since the Jack Pile method presses in all the piles without excavating the ground, the bearing capacity of the all the piles can be checked. It was investigated as a safe construction method unlike other small-diameter pile construction methods during underground extension.
