This volume is intended to provide an up-to-date overview of the approaches, methodologies and techniques devoted to better understanding of the weathering conditions of rock masses on slopes. According to the local conditions, a variety of slope ...

Abstract

Some huge landslides have occurred in deeply weathered rock, but most geologists and engineers do not appreciate the great depths that weathering can attain. Rocks can be weathered to depths of hundreds of metres, often in a very irregular ...

Abstract

Soil deterioration is one of the main causes of slope failure in hard clays and clay shales, but so far a clear general framework of the causes of deterioration is still missing. Based on laboratory data, field observations and speculation, this ...

Abstract

The paper assesses the contribution of mass movement to the development of landforms in weathered granite and gneiss terrain, using examples from SE Brazil, southern Mexico, SE China, and other locations. The style of slope failures varies ...

Abstract

The strength degradation of two marl formations (Pamplona marls in Spain and Abadia marls in Portugal) is analysed in the paper. In the case of Pamplona marls, a number of large-scale direct shear tests on natural and saturated specimens of the ...

Abstract

This paper reviews the nature and mechanics of landslides in the weathered terrain of Hong Kong. The vast majority of landslides are very shallow (a few metres depth) and occur during intense rainstorms. Deeper-seated landslides, in contrast, ...

Abstract

This paper reviews approximately 40 years of studies focused on landslides in weathered crystalline rocks of Calabria, southern Italy. In these studies geological, geomorphological, mineralogical, petrographical, engineering-geological and ...

Abstract

Lalibela is located in the northern–central part of Ethiopia, c. 600 km north of Addis Ababa in Northern Wollo (Ahmara Region). The town, which has about 12 000 inhabitants, is situated at an altitude of 2500 m. In its centre a unique complex of ...

Abstract

The Hunters Crossing landslide is a slow-moving, weathered rock slide affecting a small community of condominiums in the town of Waynesville in the Blue Ridge Mountains of Haywood County, North Carolina. In November 2005, studies were begun to ...

Abstract

Research on the properties of residual soils has been continuing in Brazil since the pioneering work by Vargas in 1953. A great number of earth dams built since then and the initiation of graduate courses since 1960 have increased the rate of in-...

Abstract

The interrelationship between slope deformation and fault-induced weathering as a predisposing factor for the development of sliding is analysed through several case studies from the Western Carpathians in the Czech Republic. The study area ...

Abstract

To clarify the erosion processes on a marly bare slope in the southern Alps, the erosion processes on a steep and erodible slope composed of Black Marls formations were observed using a time-lapse video camera. The observations revealed that ...

Abstract

A new correlation is proposed between the residual shear strength and the methylene blue value (‘value of blue’; VB) for weathered clay soils on argillaceous bedrock and on alluvial soils in the Oltrepo Pavese area (Northern Italy), which can be ...
