Abstract

As the population in cities all over the world is increasing, the effects of climatic action on the resilience of communities is becoming more and more important. Cities situated in deltas are also under strong urbanization demands and these demands have to be met with due consideration of the challenges presented by climate change, land subsidence and sea-level rise. Within this context, the local geological conditions in the Netherlands present a particularly pressing challenge where water pressure under a clay cover may increase. The static equilibrium of the cover layer might be adversely affected, and uplift failure can be imminent. A recent research program into this failure path has been initiated. Besides the field tests and advanced numerical modelling approaches, the research program also made use of centrifuge tests to quantify the extent of uplift, cracking, and deformation phenomena. This contribution intends to exhibit the aspects of the centrifuge tests conducted as part of this study. The experimental setup design and design considerations will be explained as well as the instrumentation methodology and the reasoning behind the instrumentation choices. This contribution aims to improve the stability assessment of dikes under uplift conditions.
