For comparing the anti-explosion performance of three different material arc structures, the corresponding numerical simulation was conducted by using element program LS-DYNA3D. The arbitrary Lagrangian-Eulerian (ALE) algorithm was used to simulate the dynamical matter, such as the forming process and development disciplinarian of explosive cavity. According to simulation, the propagation of the stress wave and the influences of soil layer were studied, the size of blast pit, the damage form, stress contour, pressure time curve and energy time in three different material arc structures were comparatively analyzed. The research shows that the RPC arc structure element can endure more principal stress, so it holds the stronger capability to absorb the energy from explosion, thus the RPC arc structures possess the predominant capability of the prevent collapse and integrality of the structure.
