In this paper, we, first, obtained resistance and spring constants acting on buried pipelines when subjected to ground settlement due to liquefaction by an experiment of lifting up piles in liquefied ground. Second, we investigated the suitability of the spring constants by comparison of the result by a different experiment using a dual sinking soil box with results of non‐linear analyses using transfer matrix method. Furthermore, we proposed design formulae and equivalent spring constants of the liquefied ground. The formulae were obtained by beam theory on an elastic foundation and the equivalent spring constants were determined such that calculated values of pipe responses by the proposed formulae are well matched with the result of non‐linear analyses. キーワード（英）： - 記事区分： - 区分 　　　　論文集
