The paper describes the engineering geological conditions in the mountain site of Olympic construction area (Krasnaya polyana, Adler region, Sochi). The widespread slope processes (rockfalls, landslides, mudflows, etc.) are shown to be controlled by the structural and tectonic features of the area as well as by its geological history, including the slope formation in the recent time. It is emphasized that the analysis of mechanisms and succession of slope process development are important for assessing and forecasting the general and local stability of rock massifs. These forecasts should be taken into account upon adopt­ing planning and construction decisions for major engineering objects.

Key words: mountain slopes, geological history, structural and tectonic features, landslides, rockfall, succession of slope process development, stability of rock massifs.

The technique and results of geotechnical monitoring are considered upon the oil-field development in Nenets autonomous region. It is shown that the application of special technologies for constructing oil-recovery facilities on pile foundations and for filling soil grounds 2.0—2.5 m high above the tundra surface allows us almost to eliminate the thermal influence of engineering structures on permafrost. The conditions are determined, upon which it is possible to provide the economic and potable water supply for oil-field workers using the limited subsurface water resources confined to tundra lake taliks.

Key words: Nenets autonomous region, permafrost, temperature wells, melted zones, underground water, monitoring.

The influence of animals on the geological environment is most pronounced in low-stable ecosystems. Consequences of the impact of wild and domestic animals on the geological environment are discussed. A conclusion is made about the necessity of systematic study of fauna as a factor affecting the geoenvi-ronmental conditions.

Key words: ecosystems, influence of wild and domestic animals on geoenvironment, desertification, pas­ture digression, autochthonous and allochthonous species of animals.

The extensive procedure of diffractometric geochemical analysis of snow samples has been elaborated for the first time, which permitted researchers to study the composition of aerosol solid phases in some cities and industrial cities of Irkutsk oblast. It is found that solid particles, being indicators of natural-anthropogenic systems, manifest fiborgenic activity and carcinogenic properties.

Keywords: solid aerosol phases, procedure, diffractometric analysis, snow cover, natural-anthropogen­ic systems, CisBaikalian cities.

Disagreement between the administrative and natural boundaries is one of the reasons for the low effi­ciency of nature-conservation management system. The administrative borders of the Russian Federation subjects have historical, demographic, ethnographic, social, economic and natural background. However, upon the differentiation of regions, the natural factors are insufficiently taken into account. The present article considers the interrelation between the administrative and natural borders by an example of ad­jacent subjects, i.e., the Novosibirsk region, the Altai krai and the Altai republic. The former borders fix the spatial limits of controlling bodies activities; while the latter reflect the spatial limits of natural and natural-technogenic systems. Geoecological discrepancies are revealed and the offers on possible change of administrative borders are made for the considered territories, which may improve the quality of accepted administrative (including nature-conservation) decisions.

Key words: natural and administrative borders, frontier territories, landscape division into districts, geoecological factors, geoecological estimation.

Results of the combined seismic and meteorological observations are presented that have been carried out in a local area in the southeastern part of the Fennoscandian Shield manifesting the elevated tectonic activity in the Holocene. The highest level (by our data) of microseismic emission at the Karelia territory has been revealed. The dependence of its intensity on the atmospheric pressure has been shown. The brief description of the geological structure in the area, amplitude-frequency characteristics, and the space-time distribution of microseismic signals are presented. The relation of microseismicity to exogenous factors and geological features are discussed.

Key words: Fennoskandian shield, microseismic emission, modern activity, exogenous and endogenous factors, fault structures.

Some methods are proposed for determination of the minimal strength characteristics of a thawing soil, i.e., cohesional coefficient of friction. These characteristics correspond to the shear strength at the thaw­ing limit. Their values are considered both with and without the account of the active pore pressure influence. Based on the experimental data, the equation is derived for the calculation of minimal experi­mental strength characteristics of thawing clay depending on its physical propoerties. The slope stabil­ity coefficients are compared with that have been obtained for the minimal and maximal shear strength conditions.

Key words: thawing soil, cohesion, coefficient of friction, stability of slopes.

A method for the estimation of conductivity coefficients in network model (kx,y) blocks is developed for finite-differences modeling of the mass transfer in a gypsified fractured-porous rock massif containing groundwater. The values of kx and ky are determined taking into account the predominant form of mass transfer (convection or cross dispersion) giving rise to dissolution of the maximal gypsum amount. This method was used for the modeling of longitudinal filtration in gypsified rocks in the dam bottom of Nizhne-Kafirnigan hydraulic power system (Tajikistan). The rock permeability change was the criterion for selecting filtration-control measures. It was established that a leaching zone was formed within the area of the curtain and blanket during a 100-year-long computational period in the "background" condi­tions of filtration gypsum. During this time, the total outflow through the tail bay may increase by no more than 10-15%. Under these conditions, the grouting is a tool to enhance dam reliability.

Key words: dam bottom, mass transfer, gypsum; dissolution, gypsum leaching zone.

The critical analysis of actual normative documents is presented in respect to evaluation of engineering geological conditions for construction. It is shown that SP 11-105-97 regulations concerning specific extremely hazardous, technically complicated and unique engineering structures do not correspond to modern demands. A new approach to evaluationg of complexity categories of engineering geological conditions is suggested based on broadening and specifying the factors considered, and introducing quantitative criteria for their assessment. This work was performed for actualization of engineering sur­vey standards for allocation, projecting, and constuction of nuclear power plants.

Key words: engineering geological survey; categories of engineering geological conditions complexity; factors and criteria of assessment; extremely hazardous, technically complicated and unique engineering structures; previous investigation degree.
