| Summary |
"Local site effects can play an important role in modifying the intensity of ground shaking and earthquake damage. The process of rock motion propagating through the soil column can be approximated using one-dimensional site response analyses. To evaluate the likely site response several input parameters are required. These include: thickness of the unconsolidated soil cap, shear wave velocity, unit density, dynamic soil properties, and acceleration time histories. Considerable uncertainty often exists in regards to these input parameters. In this study, the program Shake2000 was employed for site response analyses and sensitivity analyses were performed to determine how the uncertainties in soil cap thickness, shear wave velocity, and input ground motion affect predicted site response. These evaluations were made for PGA, 0.2 sec, and 1 sec period for spectral accelerations and amplifications"--Abstract, leaf 3. |
