Abstract
This research deals with modifying improvement techniques by using a new technology depending on the properties of the subsoil and the surrounding soil. Jet grouting is one of these techniques utilized instead of normal deep foundations, such as piles, peers, and raft foundations, because it increases the bearing capacity, reduces the settlement, and decreases permeability. In this research, the effect of double-pile and (2*2) jet column piles was studied in the laboratory by employing a jet grouting machine for sand soil, and the results were compared with those of similarly distributed concrete piles. Moreover, the two groups were theoretically analyzed with the 3D ABAQUS finite element software. It was found that with the jet pile, the applied load is greater and the settlement is smaller than that with the concrete pile. The ultimate pile ratio obtained through laboratory tests in the (2*1) jet pile and the concrete pile groups was 71.2% and 75%, respectively. The settlement ranged from 0.00135 to 0.00148 m with the jet pile and ranged from 0.034 to 0.035 m with the concrete pile.
