Abstract：To quantitatively assess the disaster effects of the “8 · 12” explosion in Tianjin port, the data from the public reports were collected and sorted out, and the energy of the explosion (i.e., TNT equivalence) was evaluated using different methods based on the four key factors such as the particle vibration velocity, blast energy, features of explosion crater and damage radius of building. The assessment results were verified based on the personnel casualties, the damage conditions of buildings, and the proportional distance of TNT equivalent using the calculation method in related manuals. The results show that the equivalent TNT charge masses predicted by different methods agree well with each other, and the energy of the explosion is equivalent to 500 tons of TNT.
