PROBLEM TO BE SOLVED: To provide a pipeline network analysis method capable of rapidly, easily and collectively executing pipeline network analysis for a pipeline network group hierarchically constituted by a plurality of pipeline networks differed in pressure section. SOLUTION: This method comprises a first steady analysis process for performing steady analysis while laying a virtual conduit in an interrupted state to at least a downstream pipeline network of a connecting point, by use of pipeline network data including node information for nodes constituting each pipeline network, conduit information for conduits mutually connecting nodes, virtual conduit information for the virtual conduit virtually connecting a plurality of connecting nodes set in the connecting point between pipeline networks in superposition, and demand information; a load adjustment process for executing load adjustment processing between pipeline networks for adding, based on the steady analysis result in the first steady analysis process, a supply quantity calculation value in the downstream connecting node from the connecting point to a demand set value of the upstream connecting node to set a new demand quantity; and a second steady analysis process for performing steady analysis while reflecting the demand quantity set in the load adjustment process to at least the upstream pipeline network from the connecting point.
