摘要：
To research the failure characteristics on the extraordinarily fire explosion accident which happened in Tianjin Port, through detailed site investigation and related numerical calculation, a new formula of the shock wave overpressure which can be used in near field and far field are proposed, and the formula was contrasted and validated with the actual damage. Finally, according to the explosive power and the distance from explosive source, the damaging range is divided into different damage levels. In this paper, some salient characteristics of the fire explosion accident are discovered and discussed. The results indicates that this model can depict the damage situation well in near field and far field and it can supplement and revise the planning on earthquake resistance and hazardous prevention.
