1. introduction mountain regions are increasingly endangered by a variety of disaster, including avalanche, debris flows, and rock slide. some characteristics such as elevation, angle of slope, vegetation and climatic elements could affect the avalanche event. indeed, avalanche is the second factor in soil erosion that causes demolition; therefore, it threatens the food safety. iran has two mai...

The geomechanical classification SMR (Slope Mass Rating) enables the preliminary assessment of the susceptibility of rock slopes to failure. The SMR index is obtained from Bieniawski’s basic RMR (Rock Mass Rating) through an “adjustment factor” and an “excavation factor”. Since its appearance in 1985, this classification has been used for appraisals and preliminary studies in many countries. Th...

Following earthquake events multiple soil slope failures are observed throughout the structurally fragile soil and rock in North Island, New Zealand. Many of these slopes are located in close proximity to various assets including residential buildings and roads, resulting in damage to the structures. Limited mitigation solutions are available to stabilise both the global integrity and surficial...

in this paper, after collecting the rock samples from eight mines and one high way slope, the tests for determination of dry density, uniaxial compressive strength, tensile strength (brazilian test), elastic modulus, schmidt hammer rebound number have been done on samples. in addition, in order to calculating the mean size of rock grains, quartz content, hardness and abrasivity, a thin sections...

Landslides associated with hillside cuttings in igneous rock saprolites are a serious natural hazard in Hong Kong and have been extensively studied by government agencies and local universities for many years from the perspective of soil and rock engineering. A review of the case studies for some major landslides, especially deep-seated landslides, shows certain puzzling features. First, a numb...

Digital elevation models of two “steady-state” mountain ranges, the Olympic Mountains (OM) and Oregon Coast Range (OCR), are used to examine relationships between slope distributions, the development of threshold hillslopes, and steady-state topography. Plots of drainage area versus slope for these mountain ranges exhibit substantial scatter that complicates comparison of range form to analytic...

The paper discusses operations aimed at creating a safer natural or man made rock slope by artificially inducing the displacement of unstable elements by blasting. A detailed analysis of the problems with the use of explosives present when conducting these activities is carried out focusing on the advantages and disadvantages of this technology. The results of two examples of demolition of inst...

This paper aimed to review and compare the conventional and advanced numerical techniques used for stability analysis of rock slopes. Two important methods of probabilistic limit equilibrium analysis and distinct element method are used to check the stability of northern abutment rock slope of Gotvand dam (iran) and the advantages and disadvantages of each method is discussed. The results of th...

Glacial reworking of paraglacial rock slope material has been inferred from long-deglaciated terrains to be an important component of glacial sediment transfer. We provide the first description from a contemporary glacial environment of the geomorphological consequences of glacier advance (of the Feegletscher Nord, Switzerland) across a paraglacial rock avalanche deposit. The landform-sediment ...
