Abstract

Abstract

Polymer materials have the characteristics of fast forming and good expansion performance. Their composite structures with gravel and reinforcement have obvious advantages in foundation treatment and urban road void removal and reinforcement. As reported in this paper, polymer gravel slabs and reinforced polymer slabs were designed and manufactured, and experimental study under contact explosion impact was carried out. The damage characteristics of the two kinds of slabs were investigated through the damage sizes and the measured shock wave data. Based on the ANSYS/AUTODYN nonlinear explicit finite element program, the damage modes and damage diameters of the reinforced polymer slabs were explored, and compared with the experimental results to verify the accuracy and applicability of the established finite element model. The sensitivity of the reinforced polymer slabs to explosive quantity and slab thickness was analyzed parametrically, and the prediction formula of the failure diameter of the top surface and bottom surface of the reinforced polymer slab was proposed by using a multi-parameter regression procedure. The results show that under the action of air contact explosion, the damage mode of the polymer gravel slab is mainly local collapse and perforation at the contact part. Under the impact load of contact explosion, punching and cutting explosion pits appear on the top surface of the slab, tensile failure and collapse area occur on the bottom surface, and a through failure hole is formed in the center of the slab, in addition to some damage cracks. Under the action of air contact explosion, the reinforced polymer slab mainly exhibits crater damage on the top surface, spalling damage on the bottom surface and central punching perforation damage. The reinforced polymer slab has a good attenuation effect on the explosion shock wave. The diffuse reflection effect of the closed bubble in the polymer structure on the shock wave can absorb more energy to alleviate the explosion shock wave, indicating that the polymer has the potential to be applied to the anti-explosion shock protection.
