| Abstract: | Based on the finite element method, the character of double-row pile retaining structure in pit engineering has been analyzed, the axial force, shearing force, bending moment and lateral displacement of front-row and rear-row piles have been got. The influence of pile spacing on lateral displacement of pile and stability of pit have also been studied. The results will promote the design and practice of double-row pile in pit engineering. |
