Numerical modeling of earthquake impact on engineering structures on Arctic shelf

Abstract

The problem of numerical modeling of the process of initiation of seismic activity on Arctic shelf and its impact on engineering structures is considered. To describe the dynamic behavior of a geological array, the determining systems of equations of the theory of elasticity and acoustics are used with explicit identification of all geological layers. A distinctive feature of the developed approach is the full wave calculation of the propagation of seismic waves from the source of the earthquake to the day surface. Grid-characteristic method is used for numerical calculation on hexahedral and tetrahedral computational grids.
