EVALUATING HUMAN TOLERANCE UNDER THE EFFECT OF SHOCK WAVE PRESSURE FROM SURFACE EXPLOSIONS

Abstract

Protecting individuals and structures from the effects of blast loading is a critical challenge when calculating and designing defensive structures. Shock waves, fragments, and the acceleration of structures caused by explosions will cause lethal damage to humans, equipment, and structures. To ensure safety, studies and standards in Vietnam for calculating safe distances for construction and humans in mining operations and defence structure constructions have been implemented. However, detailed studies on the impact of blast wave pressure on humans, depending on the position, the posture of the victims, the direction of the blast loading, and varying degrees of impact due to weight, have not been specifically researched. Hence, this article will introduce and use UFC 3-340-02, "Structures to resist the effects of accidental explosions", to develop a procedure for assessing the safe distances for humans affected by the pressure of ground blast loading. The result can be applied to automatically estimate the survival probability of humans under the impact of blast loading on the ground.
