지진동을 받는 안벽 구조물의 내진성능 평가

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. 5 different model section describe the cases of dense soil and loose soil in the foundation, repectively, the case to which gravel backfill was applied, and the cases to which light material replacement method and sand compaction pile method was applied respectively for seisic countermeasure methods. Pore water pressures, accelerations and deformations in quay walls and grounds and analyzed. As a result, the softening of foundation and backfill soils have much influence on the behaviors of quay walls. Also light material replacement method and sand compaction pile method are effective in improving the seismic performance of quay walls.
