For the development of geotechnical construction in the complex hydrogeological conditions not only the quality, reliability and efficiency are important, but also the speed of the construction of facilities is an important factor when choosing a method and construction technology. Application of the explosion energy is particularly effective when constructing vertical protective structures of shallow shaft in structurally unstable soils. The problem of interaction of cylindrical waves in the soil environment with absolutely rigid obstacle to the establishment of the mechanism of non-destructive stress fields from the explosion of an elongated charge is studied. The soil is modeled witn nonlinear equations of three-laminated medium near the rigid structures of underground structures. For the numerical solution of the coupled problem of "two-layer soil medium - rigid barrier", the distribution of cylindrical waves in the soil environment, using Mack?Cormac finite-difference scheme. The numerical results allow us to analyze the wave processes in the system, depending on the soil parameters of the medium. The laws of interaction of explosive momentum in two-layer medium with a rigid barrier, allowing to reconcile the pressure wave in the soil strength parameters rigid barrier with regard to the type and parameters of the explosive charge are stated. |
