Аннотация: It was shown the technique of seismic hazard assessment based on comprehensive use of methods of seismic microzonation. This technique consists of four steps. The first step is to collect geological, seismological, geophysical and topographic information. Each layer according to geological engineering survey and geophysical work are assigned physical and mechanical properties (density, limit shear stress) and the P-And S- wave velocity. Next (step 2) after visualization and examination input data using GIS technologies 3D modelling of the geological environment is performed (it is created a grid each point of which is referred to coordinates of the site). The number and depth of soil are set in each point based on geological drilling data. Then (step 3) at each point seismic intensity are calculated using instrumental methods including the method of acoustic impedance and computer simulation (GRUNT program). At the last stage according to the analysis of the results of theoretical and instrumental methods seismic microzonation map are created using GIS technologies. The procedure of constructing maps uses different methods of selection areas with the same seismic hazard (kriging, spline interpolation).

Аннотация: Представлена методика проведения сейсмического микрорайонирования (СМР) с использованием географических информационных систем (ГИС) на каждом шаге. Данная методика предполагает создание 3D-модели площадки и вычисление в каждой её точке сейсмической интенсивности. Интенсивность рассчитывается на основе обобщенных спектров реакций и синтезированных акселерограмм.
The paper presents methodology to perform seismic microzonation using geographic information system (GIS) at each step. This methodology assumes creating 3D models of a site and computation seismic intensity in each point of the site. Seismic intensity is calculated based on probabilistic generalized response spectra and synthetic accelerograms.

Аннотация: Computational technology for multiprocessor computing systems of cluster architecture is developed, the ultimate goal of which is numerical modeling of wave fields generated by the electromagnetic pulse source "Yenisei" in blocky-layered geomedia. To describe the wave processes, mathematical models of the dynamics of elastic and elastic-plastic media, of porous and granular materials are applied. The algorithms of numerical realization are constructed based on the method of two-cyclic splitting with respect to spatial variables. Computational experiments showed that the proposed technology allows reproducing the system of waves near the region of excitation of seismic oscillations in 3D setting with a high degree of details and accuracy. The results of computations can be used in working out the optimal modes of functioning the source "Yenisei", when mechanical characteristics of the layers vary in a wide range from solid and frozen grounds with inclusions of rock till granular and clayey water-saturated grounds. Numerical analysis makes also possible to obtain the averaged data, necessary for the adequate simulation of the localized pulse action from the source, using simplified mathematical models for calculating the synthetic seismograms of reflected waves over large scale and at great depth of layers bedding in complex geomedia. © Published under licence by IOP Publishing Ltd.

Аннотация: The northern territories of Eastern Siberia are characterized by a permafrost-taiga structure of the surface layer of soil, which reduces the efficiency of geological exploration using seismic sources of explosive and vibratory types. Therefore, Geotech Holding Company developed a special eco-friendly electromagnetic pulse source "Yenisei", which seismic waves are the subject of analysis using high-performance computing in this paper. Computational technology, worked out previously for solving the problems of the dynamics of viscoelastic, elastic-plastic, granular and porous media, is applied to the analysis of wave motion of a soil near a point of perturbations. It is shown that the main frequency of generated strain waves substantially depends on the elastic characteristics of a soil in the near-surface zone. A comparison of the results of computations obtained in the framework of the model of static loading with instant unloading and the model taking into account the monotone loading stage with subsequent pressure relief showed the validity of the hypothesis about the presence of added mass of a soil under the loading platform. This mass accumulates impact energy and emits seismic waves due to oscillatory motion. © 2019, Peter the Great St. Petersburg Polytechnic University.
