Fibre orientation in fibre-reinforced sand (FRS) is highly anisotropic due to compaction during sample preparation or field construction. This makes the mechanical behaviour of FRS, such as strength and dilatancy, dependent on strain increment direction. While constitutive models that are able capture FRS have been proposed for conventional triaxial compression extension conditions only, this p...

The theoretical basis of classic geotechnical engineering stability problems is limit analyis thereom. Incremental loading finite elements and strength reduction finite elements were put forward by Zienkiewicz in 1975 and the methods are called by the authors Limit Analysis Finite Elements (abbreviation LAFE for short). It has been successfully applied to slope engineering, and used to bearing ...

--For many years, large explosions within the Caltech seismic network have occurred periodically at a quarry near Corona (75 km southeast of Pasadena) and at the Eagle Mountain iron mine (240 km east of Pasadena). Explosions have taken place almost daily since 1948 at Eagle Mountain. The long-established station at Hayfield, very close to the mine, permits accurate determinations of apparent ve...

Controlling brine flow is important for the safe disposal of radioactive waste in salt rocks. Thermal and mechanical processes can have a significant impact on flow, although this has never been thoroughly investigated. In study, we conduct fully coupled THM modeling analyzing rock salt, considering non-isothermal two-phase through deformable porous media. To rigorously represent behavior, inco...

Soil–structure interfaces typically exhibit a shear behavior that is independent of the direction relative displacement due to symmetry in solid material's surface profile. This experimental study investigates interface surfaces with asymmetric profiles inspired by scales snake skin. The results box tests on two sandy soils indicate peak and residual strengths dilatancy are greater when soil di...
