Recently Released Paper - An Experimental Evaluation of Helical Piles as a Liquefaction-Induced Building Settlement Mitigation Measure

Recently Dr. Ramin Motamed, Associate Professor, Department of Civil and Environmental Engineering University of Nevada Reno, released a paper that details the results of conducting simulations of a seismic liquefaction event using a 2.9 meter tall laminar soil box that was positioned atop a shake table located at the Powell Laboratory at the University of California San Diego facility.  Dr. Motamed and his team constructed a shallow foundation that was positioned on top of a three-layer deposit configuration of sand - a dense layer, followed by a loose layer with a crust layer on top.  (4) helical piles were installed and attached to the simulated shallow foundation with side load brackets.

This study was funded by PEER -

Pacific Earthquake Engineering Research Center
