【 摘 要 】

Quality assessment of dikes is being set up in the Netherlands. The existing placed block revetments are a part of this assessment. In cases where a routine assessment is insufficient to come to a definitive conclusion, legislation prescribes a more advanced assessment. In this paper, the possibilities of such an advanced assessment are investigated. Three locations were selected for this assessment. The paper describes the experiments, field tests and calculations performed and concludes with the results of the assessment. Permeability of filter layer and cover layer appears much lower than expected, which influences the possible failure mechanism. The residual strength of a clay layer of0.8 m underneath the blocks appears to be limited.
