The invention discloses a cable double-row pile (wall) supporting structure, comprising front-row supporting piles and rear-row supporting piles. The front-row supporting piles are connected by a first crown beam. The rear-row supporting piles are connected by a second crown beam. The first crown beam and the second crown beam form a truss. The structure is characterized in that the front-row supporting piles extend out of ground to form cable columns (frames). The rear-row supporting piles are flushed with ground. At least a prestressed cable is arranged between the cable columns (frames) and the rear-row supporting piles and between the front-row piles and the rear-row supporting piles. Angles between the prestressed cables and the truss and angles between the prestressed cables and the supporting piles are smaller than 90 DEG. Cables and rods are used to connect the front-row supporting piles and the rear-row supporting piles, so as to provide stable support for the front-row cable columns (frames), and improve anti-bending rigidity of the supporting structure. When a foundation pit is excavated, the front-row supporting piles share soil pressure, and the rear-row supporting piles have dual effects of supporting and retaining, and anchor-pulling. The structure does not have inner supports, and the cables can be recycled, and economic benefit is good.
