The fluid dynamics simulations were carried out to clarify the blast pressure mitigating effects of dike's configuration in hemispherical explosion. For the simplification the back step model could be applied under the small condition for 9, the angle formed by the ground and the line between the explosion core and the dike front corner. From the simulated results, it is clarified that the large 9 provided the great reduction of the blast wave pressure at faraway position. On the other hand, in the small 6 condition, although the peak overpressure recover to the no dike pressure at far place, the mitigated area was formed behind the dike end depending on the dike end position and the height.
