The present paper proposed design formulae and equivalent spring constants of ground used for design propose of buried pipelines subject to large ground settlements. The formulae obtained by a beam theory on an elastic foundation can estimate joint rotation angles and joint expansions as well as the maximum bending strains of the pipes. The equivalent spring constants of ground were so determined that calculated values of pipe responses by the design formulae including spring constants were well matched with many experimental values. The determined equivalent spring constants associated with an amount of ground settlements are rather conservative values from a view point of design of buried pipes. Next, resisting capacities of various kinds of pipes to large ground settlements were evaluated by using the proposed design formulae and the equivalent spring constants.
