... a framework for site investigations. They pro- posed that these complexities arise from three proc- esses: (1) processes associated with the formation of the material, (2) processes associated with its subse- quent modification by deformation and diagenesis, and (3) weathering processes.

... inaccessible rock slopes has been frequently and correctly documented as an important advantage of the technique. In contrast, relatively few published studies exist outlining the limitations of laser scanning in rock slope investigations. Bias related to conventional sampling techniques for discontinuity...

The most intensively investigated slopes are Checkerboard Creek (Watson et al. 2006), Downie Slide (Imrie et al. 1992), Dutchman s Ridge (Moore 1999) and Little Chief Slide. Both Downie Slide and Dutchman s Ridge have been stabilized using drainage tunnels...

Numerical modeling in the concept design phase led to various approaches being proposed to account for the time-dependent deformations. The approach adopted will incorporate a plastic membrane to prevent both fresh...
