Study of Analysis Method on Behavior of Seismic Type Ductile Iron Pipes Considering Decrease of Ground Stiffness in Embankment Failure
Publication: Lifelines 2022
ABSTRACT
Large-scale ground motions have often caused embankment failures. If water pipelines were buried in the embankment, the pipelines have a risk of breaking during embankment failure. Therefore, we need to clarify pipeline behavior in embankment failure and take safety measures to maintain the water flow function of the pipeline. When we analyze pipeline behavior in embankment failure, we must consider the decrease of ground stiffness influenced by large ground deformations. However, a specific method to consider has not yet been established. This study proposes an analysis method considering the decrease of ground stiffness to analyze behavior of pipelines connected with joints in embankment failure. In addition, results of the analysis were compared with measured values of pipeline behavior in actual embankment failure. As a result, the validity of the analysis method was confirmed because the results of analysis could coincide with the measured values well.
