Abstract
AbstractDeposits of till occur in the Anglian and Devensian stages of the Quaternary succession in Norfolk. These are the Cromer Till, the Chalky Boulder Clay and the Hunstanton Till, the former two occur in the Anglian stage and the latter in the Devensian stage. On the north coast of Norfolk the Chalky Boulder Clay has in the past been referred to as the Contorted Drift around Trimingham and further west, because of its chalk content, as the Marly Drift.Little work on the geotechnical properties of these tills in north Norfolk has been published. Accordingly an investigation was undertaken to determine their engineering behaviour. All these tills are matrix-dominated with clay forming less than a third of the matrix except in the case of the Marly Drift. They are either firm or stiff with low or intermediate plasticity and have shear strength values ranging between 50 and 115 kN/m2. The tills are either inactive or have normal activity and all have low sensitivity. Their consolidation properties are characteristic of stiff clays.
