Electromagnetic radiation (EMR) technology makes it possible to evaluate changes in the stress-strain state (SSS) “tunnel lining-enclosing rock mass” system at a high level of interference, and create schemes long-term EMR control tunnels (geotechnical monitoring systems). The issues variations signals are extremely important for systems: based on anomalous deviations from normal regime one can...

This paper describes a method to analyze DC electric field generated by an railway considering influence of constructions. The finite element is effective solve problem including the constructions arbitrary shape, however analysis becomes time-consuming if includes steel material having fine structure such as reinforced concrete. authors introduced modeling methods concrete structures pole and ...
