Bearing capacity of shallow foundations under blast loading depends on various factors such as the severity of the explosion, buried depth of the foundation and its materials, but comprehensive study hasn’t been done on the impact of these factors on the bearing capacity of this kind of foundations. The method of calculating bearing capacity of foundations under blast loading follows that after applying initial stress due to the soil gravity, during different loading in each step, the foundation will be placed by uniform stress. After analysis of the model in the static mode, the model will be analyzed under the blast loading again, and then the average settlement of points below the foundation is calculated. This procedure is performed for various stress levels and finally the settlement-stress graphs are plotted. This stress increasing continues until the soil failed under the blast loading. Then bearing capacity of the foundation under the blast loading is estimated by the cross-tangent method on the settlement-stress graph. The results indicate reduction of the bearing capacity and the asymmetrical settlement of the foundation under blast loading. Also under the blast loading like the static condition, bearing capacity is increased by increasing the buried depth.
