| This thesis presents shear wave velocity profiles at 25 sites shaken by the 2001 southern Peru earthquake. These profiles were collected using the Spectral-Analysis-of-Surface-Waves method (SASW). The measured profiles are being used to investigate strong motion station site response, site effects, embankment seismic compression, basin effects, liquefaction susceptibility, and lateral spreads.; Utah State University conducted lateral spread analysis at three liquefaction sites. The liquefaction susceptibility at each site was evaluated using the VS-based simplified procedure, and lateral spread analysis was performed using the Youd et al. revised multilinear regression (MLR) model.; The analysis shows all three sites were susceptible to liquefaction, and Youd et al. model reasonably predicted lateral spread displacements for an earthquake with MW > 8. This research also suggests that shear wave velocity profiles along with soil sampling can be used in lateral spread analysis. |
