Experimental and numerical studies on block type quay walls under dynamic loading

Karakuş, Hülya
In this study, the dynamic response of block type quay wall was investigated by 1 g shaking table tests for one, two, three block(s) for different frequencies using two different saturated granular backfill materials (Soil 1 and Soil 2). During the experiments accelerations, pore pressures, soil pressures and displacements are measured. Distribution of the fluctuating component of total saturated soil pressure and application point, friction coefficients between the rubble-block and block-block are determined experimentally to form a base for the “performance based design method”. The experimental studies completed with numerical studies carried out using PLAXIS V8.2 software program. Comparisons of all soil pressure and horizontal displacement results show that experimental conditions are simulated succesfully with numerical study. A case study was carried out with the site data of Derince Port, block type quay wall which is damaged during Eastern Marmara Earthquake, 1999. Horizontal displacement result obtained by PLAXIS V8.2 for Derince Port, block type quay wall is in very close agreement with the site measurements. Results of measurements for displacement are discussed in view of “acceptable level of damage in performance based design” given in PIANC (2001). The result of the study performed for Derince Port, block type quay wall using numerical model is a good evidence of the reliability of the definitions of damaged levels given in PIANC (2001) to be used in performance based methods for seismic design of block type quay walls
