摘要：
FIELD: transportation.SUBSTANCE: invention relates to the field of pipeline transport, in particular, to the bio-corrosion studies under laboratory and field conditions on the pipelines outer surface and the soil bio-corrosive aggressiveness assessing in the main oil pipelines and oil product pipelines (MNPP) laying areas, taking into account the most significant environmental factors affecting the microbiocoenosis formation. Risk of bio-corrosive processes in underground steel structures assessing method is characterized by the fact that determining the humidity in the soil, the soil mineral composition, soil specific electrical resistance (SER), soil oxidation-reduction potential (ORP), soil pH, total number of the aerobic bacteria (AB), total number of the micro fungi (micromycetes) (MF), individual classes of microorganisms, sulfate reducing bacteria (SRB), iron bacteria of bacteria (IB), after which the soil aggressiveness coefficient (SAC) is calculated by the formula: K=K*K*K*K, where Kis the coefficie
