GEOLOGICAL AND GEOPHYSICAL RESEARCHES OF GEODYNAMIC STATE OF ROCK MASS

    By crossing active geodynamic zones surface and underground engineering objects, the latter are quickly abraded, deformed with further destruction.

    By now, thousands of buildings have been researched having undergone processes of underflooding and destructions due to the influence of geodynamic zones. The method of geodynamic researches, being widely used by our specialists to solve practical tasks, is up to the modern requirements of the exact determination of active geodynamic zones.

    The main principle of complexion of methods is a system approach.

    Following the principle of the system approach by solving different tasks, interconnected, complementary methods and technical facilities of registration condition and changes of rock mass at different levels are selected.

    Contractual documentation for carrying out further works

    Methods and procedure of carrying out work are universal. However the state estimate of a modern geodynamic condition of rock mass is made on a case-by-case basis, because this state is specified by concrete mining-geological peculiarities and physic-mechanical features of rocks.

    Budgetary estimate is made up under current legislation, regulations and rules.

    Developed requirements specifications and budget for carrying out works is submitted with a customer enterprise.

    Technique of detecting and mapping tectonic structures and geodynamic zones by complex of geological-geophysical methods can be used at all stages of engineering-geological researches:

  • Feasibility study
  • Working draft
  • Working documentation
  • During geological prospecting works
  • At the stages of object exploitation and reconstruction
  • In case of interpreting data of complex researches:

  • Determining existence, location and geological nature of the objects, that gave rise to anomalies of geodynamic nature in the structure of geophysical fields;
  • Estimating the influence of revealed structures (geodynamic zones) on buildings, plant facilities and civil works; dirt dikes; pit edges, natural slopes, bulk-oil reservoirs of oil pump station, trunk oil, gas pipelines, delivery ducts, and also developing anthropogenic and environmental security measures.

GEOLOGICAL-GEOPHYSICAL MONITORING OF TRUCK PIPELINES

    Trust uses technology of examining truck pipes and objects of infrastructure that lies in geological-geophysical monitoring of revealing potentially dangerous areas of trunks, being exposed with geodynamic influence. Pipes in these areas have increased wear and tear, and in the conditions of long-run exploitation risk of emergency situation is higher.

    Research data is oriented on mapping tectonic disturbances and geodynamic zones, where at the boarder of zones with different properties of ground soil axial tension in a pipeline rises. By activating geodynamic processes in these areas loads leading to gaps and break of pipe integrity increase.

    Exploited pipelines cross numerous ravine-beam systems. Along influence of these structures clear increase of geological-dynamic processes is seen: erosion, denudation, and in separate cases piping subsidence and gravitational phenomena - landslips. By crossing erosive forms of relief bends of pipelines form in vertical surface at short distances. Small areas of aggravate tension always present in the bends of pipelines: at the edges of slopes - bends and strains. By increasing of geodynamic tensions and outer influences in such areas, loads stimulating break of tightness and integrity of pipes can locally increase.

    We offer to use this technology in trunk pipelines of Russia, Ukraine and the abroad, that will make it possible in advance:

  • Determine potentially emergency-dangerous areas in pipelines;
  • Find active geodynamic zones and tectonic disturbances;
  • Discover hidden cracks of soil separation and the surface of sliding of soil masses in the slop areas during pipe lying and exploitation of pipes;
  • Install areas of development of corrosion processes.
  • Integrating of the technology will make it possible to improve exploitation security of truck pipelines and save considerable means due to selective repair of pre-emergency areas.

    Use of this technology during engineering highways of future pipelines will make it possible to avoid considerable means when constructing system of diagnostics.

GEODYNAMIC INSPECTION OF MAIN LINES

    Open Joint Stock Company Rostov-on-Don Trust of Engineering and Construction Researches is holding measures for increasing throughput and technical security of main lines.

    Technical and environmental operating security of railroads and motorways is mainly determined with geodynamic condition of rock mass of a foundation structure. Geodynamic structures are characterized with sharp change of properties of rocks, intensive state and hydro geological conditions. Within the limits of these structures maximum in terms of soil deformations vibrations of subterranean waters occur. Unfavorable combination of natural and anthropogenic factors leads to disastrous environmental-economic consequences. In the areas of crossing railway structures with geodynamic areas of subsidence and swelling occurs and breaks the parallelism of rails.

    We offer complex of measures that includes:

  • primary examination of permanent way of division for the purpose of finding existing and potentially dangerous areas;
  • organizing of geophysical researches with the purpose of finding reasons and places of loosing firmness (deformation, damages, destructions) and providing with recommendations for its liquidation;
  • ranking areas according to the degree of danger, selection of the area for first-priority repair;
  • development of the project for liquidation of detected violations.
  • If necessary we can execute constructing-restorative works on developed projects. For solving these tasks specialists of the enterprise develop and effectively use new technology of geologic-geophysical researches with the use of hardware-in-the-loop complex.

    The use of this technology allows to avoid "sudden" incidents and catastrophes owing to the influence of geological environment to increase anthropogenic and environmental operating security of railway lines and motorways and save considerable means due to selective repair of pre-emergency areas.

    We together with foreign specialists have developed new technologies on studying geodynamic situation. New methods of researches on geodynamic mapping are effectively introduced in the objects of the near abroad, including main lines of Uzbekistan, Tajikistan and Ukraine.
