Mining in residual soils is a characteristic of some open pit mines, particularly those mines in the tropical and sub-tropical regions. With residual soils’ prevalence on the earth’s surface almost as common as that of sedimentary rocks (Wesley 2013), mining in such soils requires special understanding of the behaviour and characteristics of the re...

... is high stress supressing dilation. Figure 2 shows the influence of large particles on a failure surface, highlighting the three types of failure discussed above. According to Aydin et al. (2000), the effects of large particles on stability of slopes discussed above, do not account for position and distribution of other features such as small relict discontinuities around which slip zones may initiate and propagate. ...

Expanded polystyrene (EPS) geofoam is a lightweight compressible material that has been widely used in various civil engineering projects. One interesting application of EPS in geotechnical engineering is to reduce the lateral earth pressure on rigid non-yielding retaining walls. The compressible nature of the EPS geofoam allows for the shear stren...
