Peculiarities of solid soils breaking with explosive charges of various forms
The article examines the results of experiments, performed with the help of high-speed photography unit, and peculiarities of solid soils breaking with explosive charges of various forms of section. The efficiency of a new method of stress nonuniform field generation at the internal side of charge surfaces lengthwise the cylindrical charge through solid soils loading before the explosion, is experimentally justified. It is determined, that differently gradient stress field over the charge column (pulling stresses dominate over the compressive stresses) is realized by arrangement of charges of various form of cross section inside cylindrical surfaces. In the conditions of a testing area, using models made of optically-active materials, the character of their breaking with explosive charges of various form of cross section is examined. The comparative analysis on peculiarities of solid soils breaking with explosive charges of various forms is performed.
