A frozen soil is a multiphase medium composed of solid particles, ice, and water, and the cementation between the solid particles\nand ice strengthens with a decrease in temperature. Based on the theory of a composite solid-state saturated porous medium, a\nuniform solution for the vertical vibration of an end-bearing pile in a frozen soil is derived analytically. (e axial displacements\nunder impact loading in the time domain are calculated by using the numerical inverse transformation technique. (e solution\ncan degenerate into an end-bearing pile in a saturated soil layer as the temperature approaches the freezing point. If the cementation\nbetween the solid particles and ice is ignored, the amplitude of the displacement will be overestimated. (e numerical\nresults show that temperature has a significant impact on the dynamic responses of the pile due to variation of the ice content and,\nconsequently, of the cementation between solid particles and ice.
