R&M provided geotechnical engineering support for the Port of Alaska Petroleum Cement Terminal project. R&M identified three primary data gaps: the cyclic behavior of the tidal silt deposits, the offshore soil strength properties, and the shear wave velocity of the deep soil deposits. The team drilled borings offshore and within the intertidal area. R&M performed Triaxial and Cyclic direct simple shear tests to evaluate the behavior of the material under earthquake loading, and for use in the analysis of pile capacity. We also conducted a micro-tremor array geophysical survey to provide additional shear wave velocity data necessary to produce an updated site response spectra.
Designed to replace POL Terminal 1, which suffered significant structural damage during the November 2018 earthquake, the PCT was designed to withstand seismic events and provide resiliency for this vital facility.
