Abstract

For stabilisation works of steep rock faces, which are often created as cuttings for roads, the latent processes of weathering (such as frost, gravity and water…), must be considered, in addition to fracturing and stratification, to a greater extent for “soft” rocks than in the case of hard rocks.

The selection and design of engineered structures and the life cycle of the structures clearly depend on how the weathering processes and their dynamics are considered. In many cases, this has relevant economic effects. It is not uncommon to have to weigh up what is necessary, and likewise the engineer has to go to the limits of still feasible technical solutions. Not only in nature, but also from cut slopes, water can flow out directly and act as water pressure on large rock bodies or flow through the weathered material behind steel wire mesh.

Selected examples will be used to show these processes, the associated geotechnical solutions and recommendations. One example will show how extensive monitoring can be part of a permanent solutions.
