| Abstract: | Based on continuous elastic model, some theoretical formulae of pile dynamic and static siffness are obtained from the analytical solution of vertical vibration of piles with finite length, and the influences of some relevant parameters of piles and surrounding soil on the dynamic and static stiffness are to be analyzed. It is indicated that variation principle of ratio of dynamic stiffness to static stiffness is very complicated, and therefore, the application of the ratio should be very carefully studied. |

| Keywords: | pile dynamic stiffness static stiffness continuous elasticity |
