As a kind of foundation treatment method, dynamic compaction can quickly improve the bearing capacity and compressive modulus of foundations, with characteristics such as short duration, good effect, and low cost. However, the huge vibration waves caused by dynamic compaction tend to affect the stability of surrounding buildings and slopes. Therefore, it is of great theoretical and practical significance to study the propagation law of dynamic compaction vibration waves. In this study, combined with the monitoring scheme of a terrain design used in a dynamic compaction foundation project in the Yan'an New Area, we selected a site in the filling area in order to conduct field tests on the vibration acceleration of dynamic compaction. Based on these field tests, the propagation law of dynamic compaction vibration waves along the horizontal and the slope directions, respectively, were analyzed, and the effect of the energy level on the vibration acceleration was discussed. The results show that both the radial and vertical acceleration values of the vibration waves decrease with the increase of distance from the tamping point. At the same distance from the tamping point, the vertical and radial acceleration values along the horizontal direction were greater to those along the direction of the ramp. With the increase of energy level, the dynamic compaction waves were enhanced, and then both the radial and vertical accelerations at the same distance from the tamping point increased significantly.
