Abstract:By adopting the digital high-speed photography and dynamic electrical measurement technique, a scale-reduced model was designed to experimentally investigate the dynamic damage process of a horseshoe-shaped underground protective structure under impact loading. Experimental results indicate that the bottom is the weakest part of the horseshoe-shaped structure and need be protected excessively. The shock resistance of this kind of structure can be evidently improved by adding steel plates or other high-strength protecting materials in its inner layer. The scale-reduced experiment was simulated numerically by using the LS-DYNA finite element software. The numerical results are in agreement with the experimental results. It displays that the LS-DYNA finite element software is feasible to be used to simulate the dynamic damage process of the scale-reduced model for horseshoe-shaped underground protective structures.
