As a new support structure system, the double-row pile is widely used in foundations in pit engineering, slope engineering, water conservancy engineering, and other fields. It has a big horizontal stiffness and strong anti-overturning ability and has less impact on the surrounding neighboring existing buildings (structures) when it is applied. It must be mentioned that the design experience of the double-row pile is ahead of the theory, and some research has been carried out on double-row pile support structures. This work reviews and evaluates the force deformation and earth pressure on piles of double-row piles, including pile deformation damage mechanism, soil pressure distribution law, and double-row pile structure form. In addition, the problems and shortcomings of the current double-row pile research are concluded. These results have enriched the study of the mechanism of double-row piles, provided the theoretical guidance for double-row pile support structures, and laid the foundation for further theoretical research.
