Seismic Performance Evaluation of Quay Walls by Shaking Table Tests

Abstract

The shaking table tests for 5 different model sections are performed to investigate the behaviors of quay walls during earthquakes and to evaluate the seismic performance of quay walls with countermeasures. Five different model sections sre designed varying the foundation soil densities and the backfill materials. The relative densities of foundation soils are varied to be 20% and 90%, and gravels as well as light weight aggregates are used as countermeasure backfill materials. Sand compaction piles are also installed in the backfill as another countermeasure. Pore water pressure and the magnitude of accelerations and deformations are measuresed in quay walls and grounds for dynamic analysis.
