Since propagation law of near explosion shock wave is complex, estimation of three wave point Mach wave is difficult and the data can not be analyzed effectively. In this paper, propagation characteristics of air and ground shock wave were analyzed in theory. The trajectory of three wave Mach wave was simulated and fit according to the literature data. The simulation diagram of Mach stem height proportion was shown. The propagation characteristics of the air and ground shock wave were analyzed by comparing real measured values with theoretical values. The conclusion provides an effective theoretical basis for the following measuring point arrangement and data analysis.
Key words： shock wave; three wave point; simulation; Mach stem
