Webbstructures in both London Clay and other stiff clays (e.g. Jovicic et al., 2006). However, these models lack a firm theoretical fra-mework and are usually coupled with other plastic models. A number of advanced constitutive models have been devel-oped in recent years with the intention of improving the mod-elling of natural stiff clays.

Webb18 sep. 2024 · Low pressure water-jetting (up to 20 bars) works well in compact granular soils, whereas in stiff clays, water-jetting requires special equipment capable of handling pressures up to 200 bars. The water reduces the friction on the steel surface, hence, it reduces the resistance to driving. Pre-drilling reduces also the resistance of the soil.
