Abstract

Abstract

Ice breaking by blasting is a complex process in underwater explosion engineering. In this study we examined the fragmentation characteristics of ice cover with underwater explosion shock wave and simulated the process of underwater explosion breaking ice process using LS-DYNA. We also compared the simulation result with the experimental data and found the min good agreement. Based on this we verified the simulation model and calculated different conditions. Then, keeping the test environment unchanged, we set different detonation distances, and calculated the radius of the ice breaking hole; varying the charge dosage, the detonation distance and the ice thickness, we designed nine group simulation conditions by the orthogonal design method, and analyzed the gray relational degrees and gray incidence coefficients between radius of breaking ice hole and different factors at different levels using the gray system theory. The analytical results showed that, at 100 g of the dosage, the ice thickness is 29 cm, the water depth is 2.9 m, the detonation distance range is 0.3−1.5 m, the radius range of breaking ice hole is 0−1.1 m, and the best detonation distance is between 0.3−0.45 m. According to the analysis of the above nine simulation conditions, the influencing factors that matter most remarkably in underwater ice breaking are the detonation distance (0.3, 0.6, 0.9 m), the dosage (100, 200, 300 g), and the ice thickness (24, 28, 32 cm), in order of their importance.
