| Abstract | Protecting coastal populations requires innovative Civil Engineering solutions, as highlighted by the 2011 ToĢhoku earthquake and tsunami. To this end, dual row retaining walls are being deployed along the Kochi coastline in Japan. Mechanically, how the soil-structure system resists seismic lateral loading is not well understood however. The baseline case of walls founded in dry sand is considered in this work. Dynamic centrifuge tests of dual row walls were conducted and the performance monitored using multiple techniques. The PIV technique gives wall and soil displacements and bending moments were obtained from strain gauges. Further, the horizontal dynamic earth pressures were obtained from tactile pressure sensors. The combination of techniques allows assessment of the internal measurement consistency and together advance understanding of the system behaviour. Decomposing the temporal variations rationalises the pre and post-earthquake results. This allows the overall structural behaviour to be linked to measured changes in the soil behaviour. Dual row retaining walls are being deployed along the Kochi coastline in Japan and the baseline case of walls founded in dry sand is considered in this work. Dynamic centrifuge tests of dual row walls were conducted and the performance monitored using multiple techniques and the combination of techniques allows assessment of the internal measurement consistency and together advance understanding of the system behaviour. The displacements indicate that the walls bow out above the ground level, reaching maximum deflection at approximately 2m height and reduce on either side of this value. The magnitude of the induced bending moments, the walls will behave elastically, which implies that it is the soil plastically straining that is responsible for the overall change in the system response. It has been illustrated how a variety of measurement techniques can be combined to further the insight into the model behaviour of a dual row retaining wall. |
