Abstract

This paper discusses a range of geotechnical testing capabilities available at the University of California, San Diego (UCSD). The 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. Illustration of the capabilities are shown for soil-structure-interaction (SSI) tests of embedded structures as well as pile foundations in dry and saturated soil scenarios. 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.
