Experimental Investigation into the Effect of Spring-Settlement Support on Bearing Capacity of the Shallow-Buried Structure

Abstract:

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 structure. Numerous data was obtained during these tests. The comparisons of measured parameters were done between the structure with spring-settlement support and normal support. The results indicate that, the structure with spring-settlement support can reduce the magnitude of internal force of the structure, decrease the dynamic effects on the structure significantly, and enhance the bearing capacity.
