【Abstract】 This paper describes an experimental method to observe explosion cavity in soil by radiography and gives a servies of flash X-ray radiograms of the process in compacted soil. The explosive used is a spherical charge of PETN. From these pictures a cavity growth curve can be obtained.This paper also describes the formation and development of cracks around the cavity and presents cavity growth curves in compacted soil, porous soil, saturated soil and sand.The main features and controling factors of each cavity are roughly analysed. This paper also presents cavity growth curves for three different explosive sources.更多还原
