Abstract [en]

The paper presents a comparison between numerical modeling and explosion tests in model scale and full scale involving underground/commuter train carriages. The full-scale test was performed in an abandoned Swedish railway tunnel in September 2011. Relevant geometries and construction models of the metro carriage were exposed to closely controlled design explosions in the model scale experiments. The characteristics of the blast waves were measured at different locations. The final design of the full scale experiment was chosen based on the experiences from the model scale tests. The subjects studied were uncased explosive charges and their blast wave effects in the present complex geometry and the consequences on the structures. The results from the full scale test, the corresponding model scale tests and the numerical modelling work were compared and analyzed.
