On the base of the known experimental researches, 94 field experiments of chemical explosion were carried out to investigate contact explosion damage effects of middle-high strength steel fiber reinforced concrete plates. The design of test parameters was introduced, and damage characteristics of steel fiber reinforced concrete plates were analyzed under the contact explosion conditions with different charges and structure parameters. These damage characteristics include explosion cratering, critical spalling, explosion spalling, critical perforating and explosion perforating. The damage parameters corresponding to five kinds of typical damage forms were obtained. Preliminary analysis of the main influence factors on explosion cratering and structure spalling can provide a reference for the classification of explosion local damage and the design of local-damage-resisting structures.
