The article presents the weighting function for the points within the geodetic network. The obtained system of equations is solved by the method of least squares. In the result of solving the system of equations we found the original formula for calculation of reverse weights of any point in the geodetic network
The article considers the issue of increasing the accuracy of filling geodetic networks of quadrangles with measured by the parties by increasing the number of conditional equations. We have considered the three variants of placement of additionally measured diagonals of the squares. The results improve the
accuracy in the determination of coordinates of points within the network, due to these additional measured elements
Prospects of development of oil-extracting branch of the Krasnodar region are connected with continuation of prospecting works and search drilling in a zone of transit of the Kuban River and water areas of the Black and Azov seas. In the existing normative documents about technical researches we didn't find reflection of the rule of works on platforms of capital construction of wells on the earth and in transitional conditions. The technique of studying of engineering-geological features of territories of oil and gas fields is offered. Regional and zone factors of engineering-geological conditions of oil and gas fields are established. Engineering-geological structures are allocated. Additional types of technical researches are defined
The chemical composition of neogen-quaternary, paleogene, cretaceous and paleozoic aquifer systems in the Ob-Tomskoye interfluves area is presented in the article. The water saturation with respect to secondary minerals is described. Authors show that the waters of all studied aquifer systems are saturated with respect to montmorillonites and calcite in a less degree. The geochemical water types are identified and their distribution is described
The structural and functional properties of humic acids of different types of poorly studied soils of the Krasnodar Region: ordinary black soil or chernozem (carbonated), meadowish chernozem and gray forest soils are investigated. We define the type of humus of the soil samples studied as fulvate-humate. Using traditional indicators of humus soil conditions the regularities of soil and ecological processes involving organic matter in soils under natural and anthropogenically factorial changes in the monitoring sites are revealed. The relationship of the optical properties of humic acids with the intensity of the processes of transformation of humic substances by increasing the depth of the soil sample is shown. By NMR spectroscopy, IR spectroscopy, and spectrophotometry in the visible spectrum differences and similarities in the structure of macromolecules of humic acids in soil samples. In terms of soil contamination with oil in a field experiment, on the monitoring site we have set a trend towards to redistribution in the ratio of functional groups of humic acid macromolecules: the proportion of aliphatic fragments increases. We have revealed an increase in the share of the mobile fraction of humic substances in terms of oil pollution. The article has the most suitable justification for these processes. The results can be used for prediction the environmental state of the soil under anthropogenic pollution
Within the Terek-Sunzha gas area we have identified patterns, most of which are divided into blocks in some cases with large amplitude shear. The processes of destruction of structures took place during the period of their formation and the subsequent time and due to the strong and catastrophic earthquakes. The article provides a statistical analysis of strong earthquakes in this region during the period 1688-2008 and the regularities of their existence. It is shown that the maximum number of earthquakes took place during the period of the depths of 5-12 km and the distribution of the number of strong earthquakes at levels subject to certain matematical patterns. With regard to the analysis of the distribution of earthquakes in a single year in the whole of the globe, we obtained the correlation of the displacement of rocks from levels of existence of earthquakes and possible displacement of rocks to very catastrophic earthquakes. We have also given the forecast frequency and the number of strong catastrophic earthquakes for the period from the beginning of the formation of structures up to the present time. We assessed maximum displacements of rock blocks during this time, which is in good agreement with the actual values of the displacement of rock blocks
What we have analyzed in the article is the spatial
structure of the surface air temperature and
precipitation amount fields in the Black Sea Region.
Spatial correlation method is applied to reveal
teleconnections between surface air temperature and
precipitation measured at the meteorological stations
of the region from one hand and globally averaged
surface air temperature and atmospheric circulation
indecies from the other hand. Atmospheric circulation
indecies – North Atlantic Oscillation (NAO) and
Oscillation «North Sea – Northern Caspian Sea»
(NCP) – determine to a great extent regional
temperature and precipitation regime. The goal of the
current research is to establish probable causes and
mechanisms influencing regional climatic variations
and examining of possible connections of the latter
with the global climate change. It is demonstrated that
relations between air temperature and precipitation at
particular stations in the region and global temperature
are weak and ambigous. At the same time, temperature
and precipitation regimes are affected by changes of
phases of NAO and NCP. It means that global
warming has no direct effect on the regional climate.
More probably, global warming influences the regional
climate through the changes in the atmospheric
circulation pattern in the particular region
The article is devoted to the study of the spatial
distribution of air temperature, precipitation and their
ratio in the form of moisturizing factor of the Mayma
river basin. Calculations of the vertical and horizontal
gradients are hold. Cartographic models of the
distribution basic climatic indices are also constructed
The article examines the development of a planned
study on the clearings and roads in built-up and
forested areas, as well as for building networks. Most
often, it is recommended to use the method without
diagonal quadrangles, where in each figure measured
all four corners and the length of one of the parties,
and in the first and last rectangles – four corners and
two sides. The length of the other sides is obtained by
computing, previously having leveraged the angles in
the quadrilaterals. The disadvantage of this method is
the adjustment of such circuits in a simplified manner,
namely: the distribution of residuals arising in the
augmentation of coordinates fx and fy equally to all
augmentation. The article proposes formulas of Gauss
for direct angular notches to make the conditional
equation of directional angles, deciding which method
of least squares, find the amendments to the measured
directional angles. Introducing these amendments, I
get the coordinates of the desired points of successive
angular intersection. As it may be seen from
preliminary calculations, the errors resulting from the
use of differential corrections in the coordinates are
very small and may not have a significant influence on
the measurement result
Recently, there have been satellite-based methods
widely used to determine the coordinates of points,
which allow, without mutual visibility between
points, to pursue their coordinates. However, in
some cases, for example in forests, in urban buildings
the application of these methods becomes a
problem and it is easier to apply traditional methods.
The article describes the case of using the method of
calculation of coordinates for "the approach of Hansen"
and held to evaluate the accuracy of determining
the coordinates of the points. Some studies provide
only recommendation guidelines that the most
accurate results are obtained when the shape of the
building is shaped similar to a square. In our case, on
the basis of obtained formulae we had an analysis of
the influence of the length of the corresponding base,
and its distance from the source side on the accuracy
of determination of coordinates of the original
points. The conclusion is that the accuracy of determination
of coordinates of required points depends
on the ratio of the length of the original basis and the
baseline. The optimal can be considered the distance
equal to 0.3-0.6 of the length of the baseline. The
holding data in the study can successfully be used
for the drafting of geodetic reference polygonometries
moves and thickening of networks
