Centrifuge Experiments to Study Surface Blast Effects on Underground Pipelines
Centrifuge modeling affords a useful tool to study the effects of explosions, since a small quantity of explosives can be used at higher gravity to cause the same effects as a larger quantity under normal gravity. This permits researchers to study the effects of a large explosion on prototype scale, through experiments that use smaller explosives, using scaled models of actual structures. In the subject study, experiments were conducted at 70 g on a geotechnical centrifuge. Models of underground structures (pipelines and tunnels) were buried at two different depths below the ground surface, within model containers. Controlled explosions were conducted at the ground surface, both directly above the model structure, as well as away from the structure. The effects of explosions on the structure were recorded in the form of strain measurements taken at different locations of the underground structures at different times—before, during, and after the explosions. Results of the data from these experiments provide valuable understanding of the effects of surface blasts. The results will be useful in designing new underground pipelines and runnels as well as for developing protective retrofits for existing structures.
