| Abstract: | There are limitations when existing empirical formulas are used to compute peak overpressure values of blast effects. NND2M difference scheme Was chosen in numerical simulation of blast effects near the earth of conventional charge.Detailed comparisons of the computational value,the experimental value and the empirical value were presented,Also the reasons for the difference were discussed.It is proved that the computing method chosen in this paper is reasonable and credible. |
