Hazard And Risk

An integral component of the assessment of hazard and risk for landslides from large natural rock slopes is the examination of the likely consequences associated with failure. This in turn is inherently related to the post-failure velocity of the slide mass. This paper presents a decision analysis framework for assessment of the post-failure velocity of such slopes. The paper includes discussion of characteristics that influence the post-failure velocity and presents decision trees and supporting matrices to allow assessment of the likely post-failure velocity of translational and internally sheared compound landslides. These represent the most common classes of large rock landslides. The framework is based on data gathered from a large number of landslides from natural rock slopes and incorporates information from a study of excavated rock slopes. These landslides have been studied to determine the factors and characteristics of rock slope failures that influence the post-failure velocity. The framework provides an ability to semiquantitatively assess the uncertainty in prediction of the likely post-failure velocity and identify critical areas of investigation, which would allow for reduction of this uncertainty. The method is expected to be of most use in a quantitative or qualitative risk-based analysis for landslide safety management.

Some recent work on natural rock slope movements in the Cordillera is reviewed. Climate, geology, and seismicity combine to produce rockslides in the Mackenzies and Rockies; slower, more complex bedrock flows in the Omineca Belt; spreads and flows within the volcanics of the Intermontane Belt; and rockslides, falls, debris flows and earthflows in the Coastal and Insular Belts.Major rockslides occur on overdip slopes in sedimentary, metamorphic, and volcanic successions. Natural causes of the slides include erosion of the toes and lateral margins of the rock slopes, destruction of cohesion along discontinuities by physical weathering and solution, high pore-water pressures, and seismicity. Some of the rockslides from the Mackenzies and from the young volcanoes in the Coast Plutonic Complex have shown travel distances that are extremely high for their volumes.While no regional mapping of landslide risk has been carried out in the Cordillera, some regional mapping of landslides has been undertaken, usually as part of a surficial geology mapping program. Detailed studies of hazards have sometimes followed settlement rather than preceded it, though some useful maps of particular hazards have been produced. In two cases, landslide hazard has caused the relocation of communities. Key words: landslides, rockslides, spreads, flows, rockfalls, natural hazards, Cordillera, Rockies.

Neutrosophic Number

The stability of natural rock slopes is influenced by a wide spectrum of factors, such as mechanical properties of bedrocks and spatial distribution of discontinuities. Their specific values are typically incomplete, due mainly to the lack of effective and comprehensive methods to accurately characterize these factors, especially those inside of the slopes. The neutrosophic number is a useful tool to solve problems in indeterminate environment. This study introduces the neutrosophic theory into slope stability assessment. A vector similarity measure developed under neutrosophic environment was employed to establish a stability assessment method considering multilevel attributes of slopes. Using this method, the level of stability for studied slopes, i.e., stable, mostly stable, less stable, and instable, was determined by computing the relation indices. The method was applied to a group of rock slopes located in Zhejiang province, China, and the calculated results were compared with the reality of in situ survey. The field application showed that the developed method has a good efficiency and precision in assessing the stability of rock slopes. The obtained weight vector can reveal the key influential parameters that inherently control the stability of rock slopes.
