The invention provides a pipeline operation state assessment method and system, computer equipment and a medium, and the method comprises the steps: carrying out the equal-length segmentation of a preset number on a to-be-assessed pipeline, and obtaining a plurality of to-be-assessed pipeline sections and corresponding pipeline nodes; carrying out stress analysis on each to-be-evaluated pipe section under a displacement load, establishing a pipe section deflection control equation, and solving to obtain node deflection and node bending strain corresponding to each pipeline node; according to the length of the deformed pipe section obtained by the node deflection of the two pipeline nodes corresponding to each to-be-evaluated pipe section, the corresponding node axial strain is calculated; according to the node axial strain and the node bending strain, node pipe top strain and node pipe bottom strain are obtained; and obtaining a state evaluation result of the to-be-evaluated pipeline according to the node pip
