Abstract
Buffer effect of trees on blast pressure which is due to the energy consumption to blow down trees and spatial deminution was given by following formula.<BR>Formula to determine the speed pressure Ps(kg/m2) resulting from explosion<BR>Ps=6×104(3√WTNT/R)1·15...(1)<BR>WTNT (kg): explosion converted into TNT<BR>R(m): distance from the center of explosion<BR>Formura to determine the buffer effect of trees on blast pressure<BR>Pn=(Pn-1-b){P+(n-2)α}1·15/{R+(n-1)α}1·15...(2)<BR>The formula gives the answer if n=2, 3, 4, ...then, it comes to P1=6×104(3√W/R) 1·15<BR>W: explosives converted into TNT<BR>b: energy to blow down a tree (2, 403kg/m2)<BR>a: distance between trees<BR>R: distance from the center of explosion to the front edge of trees<BR>Pn: blast pressure on n tree (n=1, 2, 3, ...)
