Mathematical Model of Seismic Impact on Operating Underground Gas Pipelines
Conducting explosive works near the operating underground gas pipeline is closely connected with a problem of seismosafe parameters determination for the drilling-and-blasting works allowing both their effective maintaining,and ensuring safety of the pipeline.In existing normative documents still there are no direct instructions by seismosafe mass of a charge determination when conducting explosive works near the operating underground gas pipeline.The mathematical model for joint dynamic deformation of system soil-pipeline taking into account their contact interaction nonlinear effects is offered on the basis of researches of seismoblast waves with underground gas pipelines interaction processes.Within the offered mathematical model the complex of computing programs in the Matlab environment,based on effective numerical methods application using perfectly matched layer (pml) as absorbing boundary conditions is developed.On the basis of the developed algorithms and computing programs the calculation method for a charges seismosafe mass while conducting explosive works near operating underground gas pipelines is offered.
