Açıklama : Gravity type quay walls are the most widely used type of earth retaining structures.Although, the static design of gravity type quay walls is well understood, the dynamic response of this structure due to the strong ground shaking is still being developed. Block type quay wall is the simplest type of gravity quay wall, which consists of blocks of concrete or natural stone placed from the water side on a foundation consisting of a layer of gravel or crusheds tone on top of each. Block type quay walls that require very expensive construction stage suffers ignificantly from earthquake and the economical and social impacts of this natural event can be devastating.
This paper is a study of analyzing dynamic response of block type quay wall during earthquake considering the both soil ‐structure interaction (SSI) and fluid‐
structure interaction (FSI) systems. The following parameters: (1) weight and friction angle of the soil material, (2) wall inclination, (3) backfill inclination, (4) wall roughness, (5) surcharge at soil surface, and (6) horizontal and vertical seismic acceleration (7) hydrodynamic effect are taken into account and the magnitude, distribution and the application point of the pressures due to the backfill, and water on block type quay walls under the seismic effect are investigated. The value of deformations; horizontal and vertical displacements, tilting are analyzed by using the experimental and numerical methodologies. The obtained results from both experimental and numerical results are compatible to each other.Key Words block type quay wall, 1g shaking table test, numerical model
