EARTHQUAKE RESISTANCE OF SHEET PILE QUAY REINFORCED BY GROUND ANCHORS

Abstract

In this study a method of antiseismic reinforcement is proposed for sheet pile quay by use of ground anchors. It's validity is studied by shaking table test and 2D-FEM effective stress analysis. The observed value at Port-Island in 1995 Hyogo-ken Nanbu Earthquake is applied to input earthquake motion for the test and the analysis. In the shaking table test , residual horizontal displacement of the reinforced quay is reduced by 20 to 30 percent compared to the one of unreinforced quay, and by comparison with the experimental result and the analytical result, seismic behavior of full-scale sheet pile quay can be explained.
