Keller Seismic Knowledge Lecture: A New Probabilistic Approach

A New Probabilistic Common-Origin Approach to Liquefaction Susceptibility and Triggering in CPT-Compatible Soils.

Kevin Franke, Ph.D., PE, will present a new probabilistic procedure to assess liquefaction susceptibility and triggering for CPT-compatible soils. It eliminates the need for fines content adjustment, identifies a threshold for fine-grained soils not susceptible to liquefaction, and differentiates the liquefaction resistance of clean sands with varying mineralogy and compressibility. However, it may overpredict liquefaction-induced settlements if clean-sand volumetric strain models are inappropriately applied to clayey soils. Practical guidance is provided for handling clayey soils predicted to "liquefy."
