Abstract
A geotextile-reinforced embankment was built over soft ground. Staged construction and vertical prefabricated drains were used to obtain strength gain via consolidation of the foundation material. Settlement and pore pressure were measured as a part of construction control. Settlement, differential settlement, and rate of consolidation were predicted by simple models. Uncertainties in the predictions were evaluated to assess the reliability of the predictions. The estimated errors were compared with the measured values, and major contributors to prediction errors were identified.

The I-670 embankment was a project of the U.S. Dept. of Transportation (USDOT), the Ohio Dept. of Transportation (ODOT), Franklin County, and the City of Columbus. The embankment was designed by STS Consultants (STS) and Gale-Tec Engineering (GTE). GTE provided monitoring and evaluation during construction. Measurement and analysis of performance were done jointly by the ODOT, GTE, and Ohio State University (OSU). The work at OSU was partly supported by the ODOT and USDOT. We thank D. T. Bergado, J. M.
