Eighth International Conference on Case Histories in Geotechnical Engineering
Large Scale Liquefaction-Induced Lateral Spreading Shake Table Testing at the University of California San Diego
Publication: Geo-Congress 2019: Earthquake Engineering and Soil Dynamics (GSP 308)
ABSTRACT
This paper presents a series of large scale liquefaction-induced lateral spreading shake table tests conducted at the University of California, San Diego (UCSD). A total of 7 different experiments are illustrated with varying heights, inclinations, soil profiles, pile material, and cross-sections. The available capabilities discussed are part of overall large-scale UCSD laboratories, one of the largest and most active earthquake engineering laboratories worldwide. Specifically, testing using 2 different shake tables is discussed, one being the largest outdoor shake table in the world. The testing models were densely instrumented with top of the line sensor arrays. Instrumentation includes strain gauges, pressure and excess pore-pressure sensors, accelerometers, and displacement pots. The method of construction is presented, and the stages clearly described. A sample of results is presented and conclusions are drawn.
