Model Shake Table Tests and Numerical Analysis on Seismic Behavior of Gravity Type Quay Wall Using a Coarse-Grained Rock Waste

Abstract eng:
The 2011 of the Pacific coast of Tohoku Earthquake caused the damages of mooring facilities, such as seaward displacement of quay walls and subsidence of backfill ground. It is supposed that ground surface subsidence at quays reclaimed with coarse-grained rock waste were influenced by its volumetric shrinkage characteristic during the earthquake. In this paper, we conducted shaking table tests with laminar shear box, indicating the relationship between the volumetric strain and relative density of coarse-grained rock waste. Further, conducting shaking table tests of a gravity type quay wall, it is clarified that horizontal displacement of the gravity type quay is less dependent on density of the coarse-grained rock waste. Effective stress analysis was carried out to simulate the results of the laminar shear box test and the model quay wall test, using the same model parametars for the coarse-grained rock waste.
