The study provides the algorithm of the quantitative analysis of indicators for making technological decisions to fasten the main gas pipeline section by anchors on non-cohesive watered soils. The algorithm uses normative coefficients which are, from the fundamental point of view, has not been sufficiently substantiated. These include: the coefficient of reliability of the anchor, coefficient of work conditions of the anchorage, coefficient of reliability of stability of the object against the emersion. However, proposed dependencies conform to the principles of normalization of stability conditions against emersion of the section of the main gas pipeline taking into account fundamentals of the method of limit states. The developed method allows estimating the features of calculation of technological parameters of fastening sections of main gas pipelines, associated with the variability of the physical and mechanical characteristics of the ground along the length of the object Constructed algorithms for automated multivariate calculations provide a methodological basis for substantiation and selection of basic requirements for technological parameters that provide the necessary bearing capacity of anchors with a uniform distribution of anchors on the length of the pipeline. The paper provides examples of calculations.
