Abstract: The displacement characteristics in the top of the cantilever piles and the squeezed branch piles, and the axial force and the distribution of bending moment of these single row piles for protecting foundation excavation are analysed by model test and numerical simulation, and that is also studied for the double rows squeezed branch piles. The model test and numerical simulation show that the displacement in top of the squeezed branch pile decreases, the multiple bending moments are distributed more evenly, and the maximum bending moment decreases compared with the cantilever piles. It is concluded that the double rows squeezed branch piles have many siginificant advantages, including displacement, structure stifness, axial force and bending moment compared with the single row ones, and the double rows squeezed branch piles is a reliable and economical method to retain and to protect foundation excavation.

Key words: supporting foundation, model test, numerical simulation, squeezed branch pile
