    Abstract
  • The near-seabed explosion shock wave can cause serious damage to such facilities as submarine optical cables and pipelines. The spatiotemporal evolution of the underwater explosion shock wave can be affected by the impedance of different types of substrate. Therefore, it is of great significance to study the near-seabed explosion shock wave load under different substrate conditions. Based on the coupled Eulerian-Lagrangian (CEL) method, a numerical model of near seabed explosion is established to investigate the effect of seabed material on the shock wave load of near seabed explosions. The results show that the seabed material significantly affects the peak pressure of the shock wave within a certain range of measuring point angles of 20°–50°. The reflection effect of the near seabed increases with the increase of the explosion distance ratio within a certain range of measurement point angles of 20°–50°. When the measurement point angle exceeds this range, this phenomenon gradually disappears. The effect regions of these two types of seabed sediment are similar while their reflection coefficients are significantly different. When the seafloor sediment is soft, the reflection coefficient near seafloor ranges from 0.81 to 1.05. However, when the seafloor sediment is hard, the reflection coefficient near seafloor ranges from 0.98 to 1.33. The water depth has little effect on the peak pressure of the shock wave.
