Abstract: Research at the six facilities that make up the National Geotechnical Experimentation Sites (NGES) has included tests on minipiles, groups of driven piles, shafts drilled in rock, and full-scale bridge piers. The tests have yielded data on soil erosion under water flow, soil densification as a means of resisting liquefaction during an earthquake, pile resistance to lateral loads, and new soil characterization techniques.
