- Abstract
- This research is primarily concerned with the evaluation of the likelihood of pore pressure build-up during an earthquake. As part of a long-term project, the report reviews methods for pore pressure development and liquefaction and documents and investigates the behavior of cohesionless soils in cyclic loading. Described are the development and application of a probabilistic pore pressure model using laboratory data; the probabilistic development of pore pressure using an effective stress model; and a probabilistic pore pressure analysis and seismic hazard evaluation. A generalized methodology is presented. Recommendations for future work include the improvement and application of the models and specific research tasks for completion of the methodology. The models developed in this study are shown to be advantageous over conventional methods.
