Open publisher page 1 citations

Abstract

Intense extrusion and vibration between the soil and pile will always take place in the formingprocess of DJM pile, which makes the soil around the piles being reinforced and extruded and the physicaland chemical reaction being taken place simultaneously. The circumferential transition is formed withinwhich material transits occur from the pile to soil around the edge of soil and piles. Therefore, it is neces-sary to consider the influence of the transition on the composite ground of DJM. Based on the characteris-tics of piles and soil transition, this paper adopts transition elements, Mohr-coulomb failure criterion andPlaxis FEM to analyze the bearing capacity of DJM composite foundation.
