Abstract:
The field explosion and laboratory tests were conducted to investigate the damage of loess under blast loading; the post-blast damage characteristics, including residual explosion cavity morphology, crack distribution, compaction range, and particle breakage, were systematically analyzed to determine the extents of different damage zones. The results show that the explosion cavity exhibits an approximately cylindrical surface with spherical ends, and the radius is 0.27-0.30 m; tensile cracks form on the cavity surface, featuring radial cracks at the top and axially parallel cracks in the mid-section, averaging 0.14-0.20 m in depth; the dry density of soil surrounding the explosion cavity decreases rapidly with increasing distance from the explosive column axis(stand-off distance), and soil compaction ceases at stand-off distances exceeding 1.60 m; significant particle breakage is observed in loess near the cavity surface due to the shock waves, transforming the particle size distribution from bimodal to trimodal; the relative breakage rate decreases sharply within 5-10 cm from the explosion cavity surface, with greater breakage detected near the mid-section of the explosion cavity compared to its base; damage zones are determined into explosion cavity(stand-off distance is less than 0.300 m), particle breakage zone(0.300-0.375 m), tensile fracture zone(0.375-0.500 m), and plastic compaction zone(0.500-1.600 m), beyond which the elastic zone(≥1.600 m)prevails; energy analysis reveals that 23%-27% of explosive energy is consumed by loess damage within the shock wave range, with 89%-91% of this energy attributed to particle breakage zone.
