Abstract

The dynamic compaction method is widely used in construction engineering because of its simple construction method, good economy, and obvious reinforcement effect. In this study, the vibration propagation behavior and isolation mechanism for dynamic compaction are examined based on a field test to investigate the impact on the oil pipelines. A power function was proposed to describe the attenuation of normalized velocity for the ground vibration. The attenuated curve was varied with the number of drops during dynamic compactions. With an isolation ditch, a sudden drop of velocity for ground vibration can be observed during field tests. It means that the vibration wave of the soil behind the vibration isolation trench can be reduced to achieve the effect of vibration isolation.
