Lateral Response of Buried Pipeline through Three-Soil Site to Random Ground Motion

Abstract:

Using the pseudo-excitation method, a simple model was built to study the seismic response of buried pipeline laid through three-soil site for vertical incidence of seismic waves. Seismic ground motions are considered as stationary stochastic processes, and the cross-PSD function was established based on auto-PSD model, coherence model, and site response model. The results show that the peak bending stress depends on the properties of adjacent soils and the width of middle-soil, and appears in the pipeline near the soil interfaces.
