Abstract Only the ultimate lateral resistance of circular pile has a theoretical analytical solution，and the other piles with different cross section shapes are less studied. Based on the limit analysis theory of plastic mechanics，the two methods of numerical simulation and theoretical analysis are used to study the pile-soil interaction mechanism of piles with different cross sections，and the complete solutions or upper bound solutions of their ultimate resistance are obtained，including triangle，quadrangle，diamond，pentagon，hexagon，etc. The slip-resistance efficiency of the piles with different cross-sections are analyzed and compared. The results show that for solid piles，the sliding resistance and section stiffness of the traditional circular pile are the smallest among the various pile types under the same cross-sectional area. Under the same perimeter and the same wall thickness，the pipe pile has a good sliding resistance and the strongest section stiffness.

Key words： pile foundation lateral capacity factor ultimate lateral resistance upper-bound solution pile section shape laterally loaded pile stabilizing pile
