Abstract:
To choose cross-section of pile reasonably in the theory and engineering appliance of composite foundation, finite element method was adopted to analyze respectively, in a 3-D elastic analysis, the deformation properties of circular cross-section pile and square cross-section pile in pile group of composite foundation under horizontal load, when different multi-layered soil conditions were considered. The respective property of axial strain for circular cross-section pile and square cross-section pile at the location where maximal strain occurs under different material properties of layered soil was obtained. The variation law for the fracture point of pile which will most possibly occur along with the change of different soil layer conditions was also obtained. Then through comparing the results, maximal strain of circular cross-section pile is higher than corresponding square cross-section pile, it is concluded that the load bearing capacity of circular cross-section pile is much smaller than corresponding square cross-section pile under the condition that both of them have identical cross-section area.
