Alternative Ways To Study The Impact Of Ground Vibrations From Explosions On The Stability Of Buildings And Structures

Аннотация

The existing basic methods of studying the propagation of seismic-explosive waves in various mining- geological and morphological conditions to assess the impact of explosions on buildings and structures are briefly outlined. The results of studying the effect of the influence of the terrain on seismic vibrations during the passage of seismic explosive waves in them are presented. The issues of organizing experiments in full-scale field conditions, the time of which entirely depends on the time of drilling and blasting operations, are highlighted, which significantly slows down the stages of design, construction and operation of buildings and structures. Along with various explosions, as well as existing expensive installations and stands that create artificial vibrations for buildings and structures, it is offered detonation method for creating vibrations in the ground, both in design and construction, so and in the operation of buildings and structures. The detonation method proposed by the authors for creating artificial ground vibrations using a gas detonation unit makes it possible to simplify and accelerate the experiments and reduces labour and material costs.
