Abstract: Considering spatial mutual interaction and deformations among ring beam, middle beams, row of piles, braces and foundation soil in the deep excavation structure, the 3-D finite element analysis model is set up based on the mutual deformation theory; and specific method is settled to calculate the equivalent foundation stiffness and earth pressure. By analyzing an excavation case, the distribution rules of the inner forces, the deformations and earth pressures in the row of piles structure with ring beam are analyzed; and the results calculated with 3-D model and 2-D model are compared. Therefore, the reasonableness of calculating model and the necessity of 3-D analysis are verified.

Key words: deep excavation, row of piles, ring beam, mutual deformations, spatial effect
