The issues related to blasting in water-saturated mineral and organo-mineral soils are considered. The theoretical foundations of soil deformation by dynamic loads, the results of field studies of the parameters of explosive waves, volumetric deformations at the front and behind the front of stress waves, the patterns of distribution of small deformations of the soil mass in the middle zone of the explosion and their influence on the useful properties of soils are presented.
The results are given. research on the technology of blasting, as well as the industrial use of explosions in water-saturated soils.
The book is intended for scientific and engineering workers.
