“…The heterogeneity of the subsurface and the lack of horizontally continuous stratigraphic units represent pathways for water to infiltrate to the slip face of the slide. A combination of such factors worked together as the driving force behind this landslide and is similar to other slope failures, as reported by Maurer et al (2010), Sharma et al (2010), Gokceoglu et al (2009), Friedel et al (2006, Lee et al (2008), and Lebourg et al (2005). Melting snowpack and repeated intense spring rains in mid-April and May served to saturate the overlying sediments and add weight to the slope.…”

The largest naturally occurring landslide in New York State history began in early May 2011. Melting of winter snowpack followed by abnormally high volumes of April rain saturated the underlying glacial stratigraphy and initiated the 0.33 km 2 (82 acre) landslide on Little Porter Mountain in the High-Peaks region of the Adirondack Mountains. Downslope soil movement rates between 15 and 60 cm per day demonstrated their destructive capacity as the shifting soils caused one house to be condemned because of the unstable ground and foundation while simultaneously rendering three other houses into immediate danger. The mechanisms controlling this landslide were investigated using geophysical methods, displacement measurements, and borehole logs. Nineteen electrical resistivity imaging surveys were implemented to map the subsurface glacial features. Ground penetration radar (GPR) profiles were collected along many of the resistivity lines and additional reconnaissance lines in several other locations. These surveys identified subsurface features such as the buried bedrock surface, thick sequences of loose zones of saturated sediments and clays within the glacial till, and boulder zones. The geophysical data were compared with displacement station measurements and precipitation records, which led to the interpretation that the landslide was triggered by large infiltration and the failure surface was along a clay-sand interface. The nature of the slide is revealed as a deep-seated rotational surface within the glacial deposits instead of the bedrock debris avalanche failures that are considered typical of the Adirondack region. The results of this study assist in the Little Porter Mountain landslide characterization and hazard potential classification of similar glacial deposits on slopes in the Adirondacks region.

Bedding planes are the fundamental causes of anisotropic deformation and mechanical behaviors in slate, which will have great influence on tunnel stability. In order to analyse tunnel stability surrounded by slate, well-foliated slate in eastern Guizhou was taken as the specimen in tests. Microscopic analysis and test results show that slate can be regarded as a special continuous material. During the test, shear strength parameters and progressive failure varied when the direction of the bedding plane was changed, and two sets of reasonable shear strength were achieved by fitting. Numerical model verification is conducted before applying, and results indicate that the model can represent the anisotropic failure properties. So the model considering anisotropic shear strength simultaneously is utilized to analyse the tunnel stability in slate. When it is medium dip angle, the tunnel is significantly unstable especially for face and side walls, and at 45° (dip angle), the plastic zone depth ahead of the tunnel face can be the largest, being 1.7 times the tunnel height. The maximum deviator stress (σ1 − σ3) is centralized on the middle of the side wall, and also, the stress (σ1 − σ3) is the highest at 45° (dip angle), which will lead to shear failure.
