Outline of Final Research Achievements

In this study, we evaluated the deformation behavior of a flexible and a non-flexible pipe under a local load in a buried environment. The results obtained are as follows. 1) It has been clarified that the RC pipes to be evaluated have different manufacturers and specifications, so the rigidity in the cross section and the property of decreasing rigidity differ depending on each company. 2) In the above-ground part, the behavior of the flexible pipe and that of the non-flexible pipe showed the same tendency, but it was clarified that the behavior was different because of the influence of the peripheral ground. 3) It was possible to set the analysis conditions considering the coefficient of reaction force and the degree of compaction according to the original ground and the base material in the FEM analysis.

Academic Significance and Societal Importance of the Research Achievements

土圧の作用環境下において,管内面から鉛直方向の局所荷重を付与した際の管体の挙動および地盤の挙動を評価することができた。また,埋設管に用いられるとう性管および不とう性管などの管種においても評価を実施することができたことから,我が国のみならず世界各国で課題となっている埋設管の定量的な耐力評価手法開発に寄与するデータの蓄積がなされた。今後も継続した研究活動を続けることで,水資源の安定した配・排水機能を維持,事故などを防止できることから,適切な管理運用につながることが考えられる。
