Метод выделения объектов слабой контрастности
Authors Д.К. Большаков and С.Г. КатаевTo locate subsurface targets and other latent patterns using experimental probing signals early developed algorithm BINREL is being offered. BINREL is a modification of the method of revealing structures and it especially is competent at, when metric data are located in regular network. Used the algorithm has universal character; it not is related to particular form and nature probing signal. The algorithm permits to retrieve small targets and weak contrast on dielectric object properties.

Проведение геофизических исследований на территории Семикаракорского городища
Authors С.А. Ерохин, М.Я. Кац, И.Н. Модин and А.М. ПавловаWe carried out complex geophysical investigations on the terrain of Semikarakorsk site. The main objective of geophysical survey was to investigate cultural layer, to found out and to describe anomalies with anthropogenic origin. These anomalies helped to specify structure of the site. Some of geophysical investigations was methodical - there were measurements on objects with archaeological excavation for following comparison of archeological and geophysical results, and then we used these knowledge for archeological substantiation of other geophysical anomalies. Complex of geophysical investigations included magnetic and electrical survey. Some important results about the site structure were obtained.

Применение геофизических методов для поиска и трассирования тектонических нарушений
Authors Е.О. Саликова and М.Л. ТитаренкоThe purpose for geophysical activities was determining areas of tectonic disturbances initially defined by interpreting aero and space photos and geomorphologic surveys. Adjustment of section structure at anticipated tectonic disturbance areas was carried out by elastic wave propagation velocities as well as by apparent resistance parameter. Geological section geophysical parameters allowing to perform proper geophysical interpretation of field investigations and processing results thereof were resulted from integral geophysical surveys, covering electrical exploration and seismic survey.

Применение методов сейсмо - и электротомографии для обнаружения зон повышенной трещиноватости при строительстве трубопроводов способом наклонно-направленного бурения в горно-складчатой области
Authors C.Г. Миронюк, Д.А. Науменко and А.А. ВиндаOn the site of horizontal directional drilling in the area of Sochi (Krasnodar region) were carried out drilling, geophysical and laboratory works. Under geophysical studies particular attention is paid to the study of of the geological structure of the bedrock, identifying faults and zones of jointing. Our experience has shown, positioning of small-scale heterogeneities of the geological environment such as zones of jointing of the traditional methods of seismic and electrical exploration is characterized by low accuracy. At the same time, the joint application of seismic tomography and electro tomography demonstrates greater efficiency and reliability of detection of these zones.

Электрические зондирования на акватории Белосарайского залива в Азовском море
Authors М.А. Андреев, И.Н. Модин and Г.Б. Рязанцев Химический факультетIn the summer of 2011 in waters of Azov Sea continuous aquatic soundings (CAS) research was performed. The main purpose of the research was to find and map natural methane tanks in the coastal area of the sea near Yur’evka village. CAS technology appeared in 2006 and the present day it is the basis for performing electric soundings on water areas in Russia. Typically CAS is applied on lakes and rivers where average electrical resistance is rarely decreases below 50 Ohm.m, but during this marine survey it was about 0.7 Ohm.m, so for the research group it became the first experience of managing with such a kind acquired data. The article assess the possibility of CAS application for marine surveys, discovers the technology and methodology of CAS and also contains results of the research.

Новые подходы к интерпретации геофизических материалов
Authors А.Е. Каминский and В.Л. ЛухмановThe paper examines the interpretive techniques of both new and well known, used by us in recent times in the processing of geophysical data field. Adhering to the principle that all new - it is well forgotten old, we do not claim authorship of these techniques, and are focused on their program implementation and practical application. In the presentation of the material is quite diverse, we have tried to sustain a single style: formulation of the problem - solve it - examples of use. The proposed solutions can be used in various fields of geophysics. Therefore, we tried to select examples of its various areas, focusing primarily on seismic and electrical prospecting.

Опыт комплексирования электроконтакного димнамического зондирования и электротомографии
By А.И. АртюгинThis report focuses on the experience of complex applications of electric tomography and dynamic penetration of small-sized carrying unit. It is known that the lithological boundaries do not always coincide with the geoelectric boundaries. The electrical resistivity in the lithologically homogeneous geological layer may vary significantly, therefore, use of drilling data as parametric data for imaging in some cases leads to incorrect results. Electrocontact dynamic penetration allows to measure the relative density and of the soil to a depth of 15 meters. Geoelectric model obtained by inversion is smoothed so the geological boundaries often can not be accurately determined. Complex processing of data electrical tomography and electro dynamic penetration can significantly improve the quality of interpretation.

Результаты геофизических исследований с целью выделения зон повышенной трещиноватости пород, зон фильтрации грунтовых вод и выделения участков для проходки скважин для мониторинга
Authors А.Ф. Волынин and А.Н. Подсеваловed in the area of the village “Selchoztechnika” for the selection of sites for placement of water wells for the monitoring observations to determine the cause of flooding of the territory and the foundations of houses. The complex of methods included the method of seismic-acoustic profiling (SAP) (mapping areas of fractured karst limestone) and the method of vertical electrical sounding (VEZ) on sites allocated SAP. As a result of the work zone is found extensively damaged fractured limestone, within which identified two linear zones of heavy water-saturated rocks. It was specified placements of three bushes of wells (depth of wells of up to 70 m). 9 wells drilled entirely confirmed the recommendation. It was carried out monitoring of the changing of the hydro geological regime and composition of groundwater. The applied method can be used to solve analog problems on the areas of karst limestone.

Authors О.Н. Баранов and Е.М. ПодтёлковAt the present time for the control of engineering structures are increasingly used geophysical methods. On the road M-27"Dzhubga-Sochi" in the mountainous part of the active landslide areas erected a large number of retaining walls and retainingstructures. Many of these structures were designed and built in the 80s of XX century, and not all working documentation is preserved. Most of these facilities need major repairs. For one of these walls was necessary to determine the design features to make design decisions to strengthen the structure.According to the project organization, with the monolithic concrete cladding panel were to be bored piles. This problem was solvedby the method of GPR-survey is widely used in recent decades.
