碩士 / 國立成功大學 / 土木工程學系碩博士班 / 101 / Simplified analyses and dynamic soil-structure simulations with pore pressure generation are performed to study the seismic responses of caisson type quay walls. The results are implemented to design the details of physical modeling for shaking table tests with soil liquefaction based on the failure modes, spatial variation of excess pore water pressure, and earth pressures along the soil-structure interfaces. The numerical procedure is further extended to evaluate the effects of the rubble base on seismic responses of caisson. The failure modes of the numerical results are similar to published cases. A caisson with rubble base will induce lateral displacement and tilting toward the sea side due to liquefied backfill. Bearing capacity failure will induce for caisson without rubble base. Comparisons between the simplified analyses and numerical simulations indicate that simplified analyses will underestimate the lateral displacements in liquefied cases due to the incapability of taking into account the liquefied conditions. Consequently, numerical simulation is recommended for evaluating the displacement responses of caisson due to seismic loadings and soil liquefaction.
