The authors have applied the method of boundary equations to resolve the problem of numerical calculation of the stress-strain state of arbitrary boundaries of excavation works in fractures massifs, if subjected to various impacts. Benchmarking of the results have proven that the proposed model based on the method of boundary integral equations may be used to identify the concentrated stresses that the loose excavation boundaries in fractured massifs are exposed to. The authors have developed an algorithm and a calculation pattern through the application of the method of boundary integral equations to calculate the values of stresses concentrated around arbitrary shape openings under impacts of various origins. Any limiting process, namely, if or and any results are in line with the isotropic medium. The proposed algorithm and calculation pattern may be used to research the concentrated stresses alongside the boundaries of hydrotechnical engineering facilities.
