METHODS OF PIPELINE PROTECTION IN SEISMICALLY HAZARDOUS AREAS
The main reasons for the occurrence of earthquakes and the characteristics of seismic waves appearing during earthquakes are given in the work. The effects of these waves on pipelines are studied, the advantages and disadvantages of above-ground and underground pipelines in seismically hazardous zones are considered. The classification of the use of structures and technologies aimed at increasing the seismic resistance of pipeline structures is given. Analysis of existing structures and technologies showed that the most effective methods of protecting the pipeline are filling the pipeline with incoherent, crushed soil and the use of sliding supports and compensating devices.
