Technology of Assessment of the Pipeline Stress-and-Strain State According to Online Information of Geophysical Service of the Russian Academy of Sciences

The technology of the automated assessment of stress-and-strain state of the main pipeline on the basis of data obtained from Geophysical service of the Russian Academy of Sciences is offered. A version of its implementation is presented in the form of a program complex including the program-computation module and the geographical information system. The exploitation loads and impacts on the pipeline are considered. The stresses arising in the pipe during the passage of a seismic wave as well as stresses occurring under exploitation loads are analyzed. A method for analysis ofthe stress-and-strain state ofthe main pipeline exposed to seismic impact is developed. The presented methods and software allow one to implement a system approach to the complex analysis of the main pipeline durability under seismic loads and to the planning of engineering actions to provide the safe and reliable operation ofmain pipelines in earthquake-prone regions.
