| Abstract: | The dynamic response of the ground under the action of a rigid circular dynamic loading is studied. Cylindrical solutions are given. Based on the solutions, a practical dynamic ground rigidity is presented. Dynamic rigidity and damping coefficient of the ground and their relation are also discussed qualitatively. A practical method is presented for determination of the dynamic rigidity and damping coefficient. |
