Abstract

Strong earthquake shaking is a natural hazard threat in the Pacific Northwest. Soil failure due to strong earthquake shaking -- known as cyclic soil failure or liquefaction -- is expected to cause large ground deformations and damage to roads, bridges, and other civil infrastructure. Cyclic soil strength (CRR) is often characterized with in-situ geotechnical tests including the cone penetration test (CPT). Relationships between CRR and in-situ test data are not well established for soils in the Pacific Northwest. Portland State University, in partnership with New Albion Geotechnical has compiled a database of cyclic lab tests for Pacific Northwest soils to characterize the behavior of these soils during a seismic event. This research presents investigation into relationships between CPT data and laboratory measurements of CRR. Preliminary findings suggest that relationships exist based on soil behavior type and plasticity indices. This research provides a basis to guide geotechnical engineering and geotechnical earthquake hazard characterization.
