Numerical simulation study on dynamic response of nearshore site under underwater explosion

Taking a nearshore site as the research background, by selecting reasonable material constitutive models and state equations, a numerical analysis model of the dynamic response of nearshore sites under underwater explosion loads is established, and ANSYS/LS-DYNA is used to carry out near-field underwater explosion loads Dynamic response analysis under the action. The propagation characteristics of the shock wave in the nearshore site under the action of the explosion shock and the dynamic response change law of the nearshore site are studied. Research shows that during the propagation of shock wave, its propagation characteristics will be affected by the boundary surface; the explosive position has a greater impact on the nearshore structure, and the impact of underwater detonation on the nearshore structure is greater than that of underwater detonation.
