When double row piles are used in filling works,cross beams can be added at their waist to improve the integrity of double row piles in filling works.On the basis of introducing the construction method,based on the finite element method,the double row piles with cross beams at the waist are compared and analyzed.The calculation results show that:after the cross beams are set at the waist of double row piles,the maximum values of axial force and bending moment of the front and rear piles above the waist cross beams are greatly reduced,so the sectional area and reinforcement of the front and rear piles above the waist cross beams can be greatly reduced.
