Studying of Deformation Processes by Two-Coordinate Laser Strainmeter

International Journal of Clean Coal and Energy 2013年第2期2卷 21-23页

作者： grigory I. dolgikh V.I. Il'ichev Pacific Oceanological Institute Far Eastern Branch of Russian Academy of Sciences Vladivostok Russia

The results of experimental data processing of a two-coordinate laser strainmeter are discussed. The two-coordinate laser strainmeter consists of two laser strainmeters which measuring shoulders are oriented along the lines “North- South” and “West-East”. Measurement accuracy of the earth's crust microdisplacements of these devices makes 0 to1 nm. Working frequency range is from 0 to 1000 Hz. Processing experimental data the main attention is paid to high tides, natural oscillations of the Earth, natural oscillations of geoblocks, superficial sea waves. It is established that after separate earthquakes the natural oscillations of regional geoblocks are strongly excited. Besides, it is revealed that quasiperiodic fluctuations of crust in the range of periods from 1 to 12 min. are caused by atmospheric processes. Besides, it is revealed that quasiperiodic oscillations of the earth's crust in the range of periods from 1 to 12 minutes are caused by atmospheric processes.

New soil thermal stabilization systems for building fundaments in permafrost regions

Research in Cold and Arid Regions 2013年第4期5卷 387-392页

作者： Illia P. Rilo grigory M. dolgikh Vladimir F. Vlasov Scientific Department Fundamentstroyarkos LLC

This paper describes new building construction methods that utilize soil thermal stabilization reghnes to compensate for negative environmental wanning and anthropogenic factors that impair fundament stability. Based on long-standing research, the Funda- mentstroyarkos Company （FSA） of Tyumen, Russia has developed four primary seasonally active cooling devices （SCDs） that maintain soil in the frozen state, which are now extensively used on oil and gas facilities located in cold regions of Russia. This paper reports on the testing and validation of these SCDs in experimental conditions. On this basis, desigqls and technologies for building bases and foundations on permafrost with use of soil thermal stabilization systems, using carbon dioxide as the heat-transfer agent, were developed.

关键词： thermal stabilization system seasonally-active cooling devices carbon dioxide thermal stabilization system perma-frost soil
