Abstract: Based on nonlinear finite element method, numerical analysis is carried out to study the working behavior of composite soil-nailed wall(CSNW) in soft soil, including ground deformation and stress distribution in soil nails and leading piles. By comparing with simple soil nailed wall’s simulation, the function of the leading piles in CSNW is analyzed. It is shown that the leading piles in CSNW can significantly help decreasing the displacement of retained soil as well as change the distribution of soil deformation, reducing the tensile force in soil nails, and therefore, increasing the stability of the retained soil.

Key words: composite soil-nailed wall, working behaviour, finite element method, constitutive model, leading pile
