Abstract

Phase 1 of the project described herein is part of the Pacific Earthquake Engineering Research (PEER) next generation liquefaction (NGL) effort and will be reviewed by senior PEER researchers and their stake holders (e.g., CALTRANS). Our efforts in this proposal will focus on gathering, documenting and archiving information regarding liquefaction-induced lateral spread. The collected information will include: soil properties, site characteristics (soil layering, topography, etc.), earthquake strong ground motion, and observations and measurements of soil response (e.g., post liquefaction ground deformations) for important, well-documented historical earthquakes. Included in this data gathering will be an assessment of the inherent characteristics associated with the data (e.g., quality, uneven distribution, scarcity, uncertainty, etc.). In addition, the data will be warehoused in a spatial database, and archival and dissemination tools will be developed for future assessment and model development by interested researchers (i.e., Phases 2 and 3– new subsurface and topographic data gathering and model development). No funding is requested for Phases 2 and 3 in this proposal.
