Abstract

Loma Prieta Earthquake of October 17, 1989 caused severe damages in the San Francisco Bay Area. Field measurements made during the earthquake and analyses performed to date indicate that bedrock accelerations were amplified to 2 to 3 times in propagating through deep cohesive deposits. In view of this, the performance of a hazardous waste and sanitary landfill subjected to Loma Prieta Earthquake and founded on deep cohesive deposits was evaluated. Analyses indicate that the peak accelerations at the base of the refuse are slightly amplified in propagating through the refuse thicknesses of up to about 50 feet. For higher refuse thicknesses, the peak base acceleration attenuates significantly. Slope stability and liquefaction analyses were also performed using these accelerations. The results indicate some but small potential for plastic deformation. These results were supported by the post-earthquake field inspection and the field data collected during the earthquake.

Performance of a Hazardous Waste and Sanitary Landfill Subjected to Loma Prieta Earthquake

St. Louis, Missouri

Loma Prieta Earthquake of October 17, 1989 caused severe damages in the San Francisco Bay Area. Field measurements made during the earthquake and analyses performed to date indicate that bedrock accelerations were amplified to 2 to 3 times in propagating through deep cohesive deposits. In view of this, the performance of a hazardous waste and sanitary landfill subjected to Loma Prieta Earthquake and founded on deep cohesive deposits was evaluated. Analyses indicate that the peak accelerations at the base of the refuse are slightly amplified in propagating through the refuse thicknesses of up to about 50 feet. For higher refuse thicknesses, the peak base acceleration attenuates significantly. Slope stability and liquefaction analyses were also performed using these accelerations. The results indicate some but small potential for plastic deformation. These results were supported by the post-earthquake field inspection and the field data collected during the earthquake.
