    Abstract
  • The bubble curtain can effectively weaken the influence of underwater shock wave on the surrounding environment. In order to investigate the synergistic effect of air supply volume and bubble curtain layer on the shock wave attenuation of underwater explosion, underwater explosion tests with one layer, two layers and three layers were designed under the air supply volume of 30, 60, and 90 L/min, respectively. The results show that the attenuance of bubble curtain increases with the increase of air supply volume and layer number. When the air supply is small (such as 30, 60 L/min), with the increase of the number of bubble curtain layers, the attenuation efficiency of the peak pressure between adjacent layers becomes worse; when the air supply is large (such as 90 L/min), with the increase of the number of bubble curtain layers, the attenuation efficiency of the peak pressure between adjacent layers becomes better. Combined with the economic benefits of the actual project and the complex underwater environment problems to analyze the attenuation effect of the bubble curtain, it was determined that the two-layer bubble curtain with the air supply rate of 30 L/min was the optimal attenuation scheme, which provides reference and new ideas for related practical engineering problems.
