Abstract

Abstract

Simultaneous or slightly different explosions at multiple points in concrete medium can generate a complex superposition and aggregation effect of ground shock waves, significantly enhancing the pressure of ground shock waves in a specific area and greatly improving the destructive power of the explosion. To obtain the explosion aggregation effect and ground shock propagation attenuation law under the different arrangement of multi-point explosive sources, field tests were first carried out on single and seven-point aggregated explosions in concrete. Then, the reliability of the RHT material model parameters and the SPH numerical algorithm are verified based on experimental data. On this basis the orthogonal design method and gray system theory on the multi-point detonation parameters are adopted for design optimization. Gray correlation coefficients and gray correlations between scaled charge spacing, scaled active charge height, scaled detonation time difference and peak pressure at different proportional bursting center distances are established. Finally, by carrying out single-objective factor optimization and multi-objective factor optimization, a set of preferred combinations of the factors is determined, and simulation tests are conducted to verify the results. The analysis results show that the RHT model of concrete material and the SPH algorithm can reasonably predict the shock wave propagation attenuation characteristics of multipoint charge explosions at different scaled bursting center distances as well as the induced damage and destruction of concrete. The main factors affecting the impact of the ground shock aggregation of explosive effect, in order of magnitude, are: scaled charge spacing, scaled detonation time difference and scaled active charge height. Under the conditions of the present test, the optimized detonation parameters are found as: the proportional charge spacing is 0.549 m/kg^1/3, the proportional detonation time difference is 0.239 m/kg^1/3, the proportional active charge height is 0. This set of parameters will result in the best ground shock aggregation effect, being up to 4.7 times the ground shock pressure produced by the same amount of single-point group charging.
