Numerical Studies of the Effect of Slope Failure on a Buried Pipeline By a Hybrid Analysis Using Sph and Fem
Abstract eng: In past earthquakes, pipelines buried under roads with banking structures that are constructed across the slope of a mountain are exposed when the embankments fail. However the influence of embankment slope failure on a buried pipeline has not yet been studied. Therefore in this study, analysis of embankment slope failure is performed using smoothed particle hydrodynamics method and finite element method. The results obtained are shown below. The deformation characteristics, stress, and strain induced in the pipe that is affected by slope failure were clarified quantitatively. Furthermore, it is clarified that the exposure mechanism of the buried pipe under the slope in collapse progressing. Therefore, the results obtained by this study may contribute to earthquake countermeasures for buried pipes, and also contribute to post-earthquake recovery and aseismic design.
