摘要：

Small span arch steel structures on spring-settlement support and normal support were designed as research objects. 1kg, 2kg, 3kg and 5kg TNT group charges were detonated respectively on the center surface of backfill above the structures. Numerous data was obtained during these tests. The comparisons of measured parameters were done between the structures with spring-settlement support and normal support. The results indicate that, the structure with spring-settlement support can reduce the magnitude of internal force, decrease the dynamic effects significantly, and enhance the bearing capacity.
