Title: Evaluation of Ground Rupture Effects on Critical Lifelines (NEES-2005-0013)

Year Of Curation: 2011

Description: A suite of experiments was performed to investigate the performance of buried pipelines and conduits subjected to large ground deformations. Full-scale laboratory tests were performed at Cornell University and small-scale centrifuge tests were conducted at the geotechnical centrifuge at RPI. The tests focused on buried pipeline response to abrupt ground displacements that induce tension, compression, and bending in the pipelines. The ground deformation involves both strike slip and normal faulting. The types of pipelines investigated were composed of continuous welded steel and high density polyethylene (HDPE). The available data include soil and pipeline displacements, soil-pipeline interaction pressures, strain gage measurements at all locations along the pipelines, load cell measurements of axial forces, and lab data on partially saturated soil properties for the large-scale tests.
