TEST 15M - RCK02 : Part 2 - 9m radius centrifuge experiment on sandy levee behavior under ground motions

TEST 15M is the second part of the second investigation (RCK02) we run in the large scale 9m radius centrifuge at UC Davis. At the end of test 14M we removed the clayey levee and we replaced it with a sandy levee. This process involved several days and led to a different configuration of the model. The records of this stage could not be cataloged under the same folder of the former stage. The objective of TEST 15M was to investigate the seismic performance of the typical sandy levee on top of a peat layer we encounter in the Sacramento-San Joaquin Delta. The model was spun to 57 g modeling a prototype scale 5 m levee atop 6 m of peat. A moderate motion (representative of the Delta seismic risk) was applied to the model when primary consolidation at 57 g were reached. The report discusses in detail the setup and the outcomes.
