CDSM Ground Improvement at X-Ray Wharf, Apra Harbor, Guam
Doug Schwarm, P.E., P.Eng.
Abstract:
The US Navy's X-Ray wharf refurbishment project included a new sheetpile quaywall 10 m outboard of the WW II-era structure. Deep soil mixing was specified to mitigate liquefaction potential of the pluviated silty coral backfill.
The case-history presentation focuses on recognition, diagnosis, and mitigation of unexpected displacements that occurred during ground improvement. Project success is a testament to collaboration and the value of technical expertise in the field.
Cognizant that we are entering, finally, the last throes of a Pacific Northwest winter, this presentation deliberately emphasizes photographs of bright blue lagoon waters and fluffy tropical clouds. Sure, the work was interesting too, and this displacement issue turned out to be technically quite meaty. But this is a light presentation appropriate for welcoming warmer and dryer weather.
