... ABSTRACT ABSTRACT: Analysis of a rock slope requires a geometric description of the surface and knowledge of fracture patterns and their properties. Advances in digital technology provide tools that allow the generation of digital terrain models at the centimetre-scale. In this research...

... of the SSR system in a risk management framework for management of unstable rock slopes. Before discussion of the SSR use within a slope instability risk management framework, a brief introduction to rock slope failure, rock slope monitoring, risk management and the SSR technol- ogy is presented. 1.1 Rock...

... ABSTRACT ABSTRACT: The ability of laser scanners to rapidly provide structural data in high inaccessible rock slopes has been frequently and correctly documented as an important advantage of the technique. Researchers have also shown the potential for characterizing varied rock mass...

... ABSTRACT ABSTRACT: The importance of step-path failure geometries in the stability of rock slopes has been emphasized in recent research on high mountain slopes and large open pits. This paper documents the use of digital imaging techniques including laser scanning in the characterization...

...1 INTRODUCTION Analysis of a rock slope typically requires an evalu- ation of the rock structure, an assessment of the mode of failure and the strength of the material. Once a critical failure mode is determined, both con- tinuum or discontinuum analyses can be readily ap- plied and the analyses...

... ABSTRACT ABSTRACT: SSR (Slope Stability Rating) classification system is a new rating system which has been proposed in Iran to study the stability of fractured rock slopes of non-structurally controlled failures. In this system, the stability can be evaluated by means of slope design charts...

... for automated discontinuity analysis of rock slope. Feng & Roe- shoff (2004) used a similar approach to create a 3D solid model of fracture planes. These authors showed that the geometric characteristics of discon- tinuities, such as orientation, spacing, persistence and roughness can be obtained using laser...

After a par- ticular rock slope has been singled out for hazard as- sessment, BC Hydro s assessment process, as illus- trated by the Checkerboard Creek project for exam- ple (Watson et al. 2006), is as follows: Develop reliable geological and geo- hydrological models through...

... ABSTRACT ABSTRACT: It is difficult to predict the behaviour and failure of large rock slopes with a high level of confidence. The reasons for this include an incomplete understanding of the uncertainties contained in the geotechnical model used to develop our slope designs and our inability...
