Ingineering geological problems of high-rise construction with underground space development in Saint-Petersburg
- Authors:
- R. E. Dashko
- A. M. Zhukova
The history of high-rise construction is considered summarily. The main features of high-rise buildings and difficulties connected with theirs engineering and construction especially with underground space development and deep excavations in soft water saturated soils are characterized. Territorial construction guides «Residential and social high-rise buildings» prevail in Saint-Petersburg are analyzed in the context of recommendations for reliable basement choice. Brief description of Pre-Quanernary clays (Upper Vendian clays and Lower Cambrian clays) as basement for high-rise constructions are given. It is placed emphasis that the main feature of Pre-Quaternary clays is zone sequence of physical and mechanical properties and fissuring in depth. Physical and mechanical properties of Upper Vendian clays, Lower Cambrian clays and glacial clays are given. In addition, it is confirmed that glacial soils is not recommended to use as a basement for high-rise buildings.

Amplitude-phase correction of additional MT impedance curves for two dimensional structures
- Authors:
- E. Yu. Ermolin
The regularities of the amplitudes and phases connections of MT-impedance tensor components for 2D geoelectrical synthetic models have been considered. The amplitude-phase correction (APC) allows to improve the quality of data processing results both for the main and for the additional impedances. It also gives a possibility to suppress biased data for noise pollution data. Recommendations on accuracy rising of determination of tensor impedance components in the MT-data processing have been defined on the base of found regularities.

The depth estimation of 2D conductive isometrical bodies by singular points at the tipper frequency characteristic
- Authors:
- E. Yu. Ermolin
- O. Ingerov
The relation between parameters of 2D anomaly body and features of vertical sections of tipper amplitude are considered in this paper. According to investigations the depth of center, top and bottom of conductive body is connected with geometrical distance between two symmetrically located positive extremes in tipper pseudo-sections. In addition the tipper amplitude in extremes decreases on account of increasing depth of anomalous body. The described regularities can be used for MT projects planning and quantitative estimation of anomalous body parameters using tipper pseudo-section constructed from field data.

Two genetic types of peristerites in iridescent plagioclases
- Authors:
- M. A. Ivanov
- A. P. Simakov
Physico-mathematical modeling has shown that color of iridescent depends on spacing of peristerite lattice. The more spacing lattice, the color of iridescent is higher. The phenomenon of iridescent in plagioclases has an interferential nature. We can select two genetic types of peristerites: peristerites of decomposition and segregation peristerites. Segregation peristerites are formed from postcrystallizational consolidation of peristerites of decomposition. The form of segregation pertisrerites is one of the reasons of polychromatic iridescent genesis in plagioclases.

Optimal parameters of geotechnology of stock pile formation from pelletized gold-bearing ores were established basing on experimental and theoretical studies in order to enhance its filtration properties. In particular, exponential dependence was established of permeability coefficient on the stock pile height and the ultimate strength of the pelletized ore, its bulk weight and content of coarse particles +2 mmin combination with sandy-loamy and loamy fine grained soil. Without account of this data loss of gold within the stock pile can increase over 2 or 3 times. Basing on the results obtained application of the combined geothechnology of heap leaching of gold-bearing clayey materials of natural and man-made origin was justified.

The facial and lateral on matrix body as well as cracks along the matrix body, spalling of the matrix sectors and normal wear are attributed to the mechanical type of wear. The proposed classification includes main types of wear at jointed rocks drilling and creates the grounds for the designing of rock-distributing tool more resistant to mechanical and thermo physical wear.

The model of efficiency of the earths of forest land allows to calculate a forest stand stock on a forest plot, characterized by certain natural factors (agroclimatic and geomorphological areas, an amount of precipitation, height above sea level, a kind of quaternary adjournment). Stock-taking of communications between natural factors and efficiency of the earths of wood fund is executed, the equation of regress is constructed and its statistical estimation is executed.

During the analysis of the is intense-deformed condition pictures of distribution of horizontal pressure and vertical displacement on border ore потолочины and карбоновой thicknesses have been received. It is established that the zone of clearing works essentially influences distribution of pressure and movings to border ore roof and carbonic thicknesses. By results of modeling it is possible to estimate possibility of formation of vertical water spending cracks in an ore roof.

Physical processes that lead to the emergence of large forces of attraction between bodies, joined by anodic bonding technology result from the large electric fields strengths at the ontact interface. Nondestructive method of monitoring the strength of obtained conductor-to ionic di- electric anodic bonding seals is based on the relationship between the dependence of current versus time flowing in the formation of seals and the strength of the resulting seals. Theoreti cally justified a new technological method for manufacturing of high-quality anodic bonding seals. The results obtained are confirmed experimentally.

The paper presents a number of experimental techniques for detecting in amorphous tantalum oxide films structural defects, which accelerate film destruction processes in a strong electric field and thus are potentially dangerous under prolonged thermoelectric stresses applied to capacitor structures. It is shown that the anomalous frequency dependence of dielectric losses and increase of the leakage current over time can identify potentially unreliable capacitors.
