Стойкость ремонтируемых систем трубопроводного транспорта к повреждениям элементов сетевой структуры

Abstract

It is shown that the set of all linear elements of the system can be divided into 5 subsets G1...G5, depending on which specific nodes a particular pipeline connects. It was established that the greatest influence on the growth of resistance index values is exerted by the effect of an increase in the quantitative composition of the subset G1, and the smallest one is the increase in the composition of the subset G5. In this case, the degree of influence decreases with the transition from the elements of the subset G1 to G5. During repair operations, individual fragments or pipelines are usually excluded from the current system. Such structural applications can lead to a situation where accidental damage to several or even one pipeline will lead to disconnection of some consumers from the source. The specified feature should be taken into account when planning, preparing and conducting repair work. The existence of rational and irrational network structures, characterized by the greatest and least resistance to progressive damage, is proved. The planning and organization of repair work of pipeline transport systems is recommended to be carried out with a preliminary assessment of their resistance to progressive damage and taking into account the possibility of using rational network structures.
