- Abstract
- Assessment of the technical and economic feasibility of using high explosive detonations to simulate the effects of earthquakes on engineering structures is reported. The investigation comprised eight tasks: (1) identification of potential simulation methods; (2) development of simulation criteria; (3) analysis of existing ground motion; (4) development of a numerical calculation approach involving over 30 one- and two-dimensional calculations to expand the data base by providing insight into explosive ground motion phenomena and revealing relationships between governing parameters; (5) numerical calculations to enhance ground motions from explosive sources; (6) synthesis of data and calculation results into predictive relations; (7) application of explosives to simulate an earthquake-like environment to a specific structure; and (8) presentation of the economic feasibility of using explosives to simulate earthquake-like systems. Results indicate that explosive simulation of earthquake-like ground motions on engineering systems is technically feasible.
