GROUND IMPROVEMENT METHODS FOR THE GEOFILL PROJECT AT THE OAKLAND MOLE TOUCHDOWN

A variety of ground improvement methods were employed on the Geofill embankment to allow stable construction on soft, compressible clays and provide acceptable long-term performance. The paper presents a case study of the techniques used which included multiple geosynthetic layers to enhance construction, wick drains with surcharge fill to accelerate settlement and soil strength gain, vertical pipe drains to densify existing sandy fill, and controlled rate of loading to maintain stability. Typical geotechnical monitoring and vertical pipe drain test section results are also presented. A summary of lessons learned from the successful construction is provided to assist practitioners on similar projects.
