Abstract

This paper describes the instrumentation being developed and/or used for monitoring the post-liquefaction time-dependent changes in the state and properties of sand. As part of the NEESR project "NEESR - II: Mechanisms and Implications of Time-Dependent Changes in the State and Properties of Recently Liquefied Sands," a field study is being performed which involves the inducement of liquefaction in a saturated sand deposit via explosives, a vibroflot, and a NEES vibroseis. Subsequent to liquefaction, the time-dependent changes, commonly referred to as "aging," in the state and properties of the liquefied sand will be monitored for months to years. Central to the field study is the measurement of accelerations, settlements, and pore water pressures during and subsequent to liquefaction. Monitoring these parameters will allow the authors to compare the various methods used to breakdown the soil structure with the magnitude of disturbance and subsequent aging. Copyright ASCE 2008.
