摘要：This study investigated four types of explosion fragments generated by the detonation of a horizontal storage tank: plate-shaped fragments (PL), tube-end section fragments(TE), and Plate tube-end section fragments (PTE1 and PTE2). Applying a 150 m3 horizontal storage tank as the explosion source, the distribution of projection distances and the impact probabilities of fragments with different shapes were simulated via a Matlab program. The effects of the target tank's radius, height, and distance from the explosion source on the impact probability were analyzed. Quantitative results show that the TE-type fragments had the highest impact probability, while the PTE1-type exhibited the lowest. The impact probabilities for all fragment types decreased sharply within 0-50 m from the target tank and then declined more gradually beyond 50 m. Under the scenario of a blast wall 20 m long, 6 m high, and located 20 m from the explosion center, the probabilities of a 2000 m3 vertical storage tank at 40 m from the source being hit by different fragment types were 4.25%, 4.56%, 0.98%, and 2.05%, corresponding to blast wall protection efficiencies of 20.56%, 22.58%, 73.11%, and 38.99%, respectively. Experimental results show that fragment risk is most significant in the near-field region, the blast wall provides particularly outstanding protection against PTE1-type fragments, and the risk mitigation effect tends to level off when the safety distance exceeds 50 m. This study offers a quantitative basis for the layout and protective design of storage tanks in explosion-hazardous areas.
