“…In agreement with Larsson et al (1987Larsson et al ( , 2007, they conclude that s DSS u =r 0 p is a function of the soil's plasticity, and indicates that there is a relationship between the anisotropy ratio s DSS u =s A u and PI (Eq. ( 7)), which is valid for clays with a PI value above 10% (Thakur et al 2017). Notably, the Norwegian recommendation for s A u =r 0 p (given in the SHANSEP framework, Eq.…”

Empirical correlations provide valuable information in early design stages, and they help to validate or discard single values from site investigations. This paper presents a multivariate database from commercial projects consisting of evaluated shear strengths obtained from direct simple shear tests and fall cone tests (which are calibrated to the field vane test), including index tests. The multivariate database is used to investigate the performance of common transformation models and to test the recommended correction for fall cone tests. It is found that the measured normalised shear strength evaluated from direct simple shear tests and fall cone tests is correlated to the liquid limit and that the results conform to Swedish and Norwegian recommendations. However, the scatter is large, more for fall cone tests than for direct simple shear tests, which is thought to depend mainly on sample disturbance. It can however be concluded that the trend of normalised shear strengths increases with increasing plasticity.

“…Since there is a close connection between clay strength and pre-consolidation pressure, it is important to understand the Quaternary geology of the area of interest. This includes knowledge about the soil depositional history and subsequent natural processes that have shaped the landscape due to, for example, erosion and landslide activity (Thakur et al 2016). It must be realised that the quaternary map provides information only on the top layer of sediment deposition.…”
