Analysis on Rule of Load Transmission of Squeezed Branch Plate Pile Group Foundation under Horizon Load
The text analyses the rule of load transmission of squeezed branch plate pile group foundation under horizon load by using the 3D elastic-plasticity finite element model. The results obtain relative displacement between pile and soil, bending moment of piles, and curves of soil resistance in different position, different step load and different deepness. The results show that: relative displacement of back pile is bigger than front piles; the branch and plate affect the bending moment of pile, which breaks in the position of plate, and reduces greatly under the branch and plate; pile foundation bears horizon load by working of soil front piles. The great soil resistance presents to the head of first plate, and which has the effect of unloading to soil below the plate. Relative displacement, bending moment of each pile, stress of soil around piles has different characters which reflect the efficiency of pile group.
