Abstract

Abstract

To study evolution processes of the soil arching effect and the stress transfer law of soil arching, according to equilibrium conditions of piles and soil and the shear strength criterion, a stress transfer model of soil arching was constructed. The numerical model was built based on the engineering background, and the pattern differences of soil arching in the three stress contours were compared by controlling the equal stress difference method, besides, in conformity to the stress transfer model of soil arching, the transfer law of loads behind piles was analyzed. The analytical solution showed that the normal stress of vertical soil arching between piles and horizontal soil arching behind piles decayed in the law of the exponential function. According to the evolution process of soil arching effect with depth, it could be divided into four zones to be analyzed. The horizontal soil arching effect decayed with depth, and the stress in the soil arching and pile tip increased with depth and was gradually an approximation to the stress behind piles. The load transfer coefficients of soil arching behind piles decreased with depth, and the load transfer coefficients of soil arching between piles increased with depth.
