Corpus ID: 109749725. The slope face is vertical with a height H, the failure plane is oriented at an angle ψ, and a vertical load, L, is applied to the upper slope. The failure surfaces are usually structural discontinuities such as bedding planes, faults, joints or the interface between bedrock and an overlying layer of weathered rock. An approach for calculating distributed factor of safety of the irregular shear plane was put forward in this paper. This chapter describes the method of analysis for plane failure and demonstrates its application to the design of reinforced slopes. Four such ratios were tested, as summarized in Table I. Figure. Figure 7. The intersection of planar discontinuities in the rock mass with the surface slope is predisposing toward plane and wedge failures.

Mechanism of rock slope failure under self weight, water forces, surcharge, horizontal seismic force, and stabilizing force. Stability analysis of anchored rock slopes against plane failure subjected to surcharge and seismic loads @inproceedings{Hossain2011StabilityAO, title={Stability analysis of anchored rock slopes against plane failure subjected to surcharge and seismic loads}, author={M. Hossain}, year={2011} } The failure surfaces are usually structural discontinuities such as bedding planes, faults, joints or the interface between bedrock and an overlying layer of weathered rock. Zhao et al. Wedge Failure. Some attention was focused on the stability of Norwegian rock slopes after the destructive rock-avalanches and tsunamis in Tafjord and Loen in 1934 and 1936. Base failure occurs when there is a weak soil strata under the toe and failure plane passes through base of slope. PDF. Logout. Anchored rock slope… ±20°). Create a free account to download. Plane failure in rock slope. Footwall slope Bi-planar failure Ploughing failure FDEM DEM Brittle fracture Footwall slopes refer to unbenched rock slopes in which the slope face is parallel to a set of persistent disconti-nuities (e.g. Pablo Chang Huang. 1: Dimensions and surfaces defining size and shape of wedge. 10.1680/geot.2004.54.4.279 joints and bedding planes) would be needed for every cut-slope for the assessment and identification of potential instability problems. Hoek and Bray 31 proposed a sliding failure model for the stability analysis of a plane rock slope for which the upper sliding body includes the horizontal sliding surface and vertical tension cracks. International Journal of Surface Mining, Reclamation and Environment: Vol. A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses en masse and not in individual blocks. 21 are shown four types of failure of rock slopes: (a) plane, (b) wedge, (c) circular, and (d) toppling. Your Account. 2nd Quarter 2005 C over Story 24 and especially mapping of the geological structures (e.g. Abstract In stratified sedimentary and meta-sedimentary rock formations ‘plane mode’ of rock failure is very common. Areas subjected to slope deforma-tion can provide important insights into the actual cause of rock avalanching, and may help to identify key observations that warn or are precursors of future events. The K M Mountain land-slide in the state of Washington (Lowell 1990), The intersection of planar discontinuities in the rock mass with the surface slope is predisposing toward plane and wedge failures. Search all titles. Sliding mass is the mass of soil within the slip plane and the ground surface. A three-dimensional wedge failure analysis was presented by Coates (1967), Lond et al (1970) and Hudson & Harrison (1997). Search: Search all titles ; Search all collections ; Rock Slope Engineering. An analysis is presented here which can take these factors into account. A three-dimensional wedge failure analysis was presented by Coates (1967), Lond et al (1970) and Hudson & Harrison (1997). Major plane failure in granite rock slope. However, as the scale increases, simple structurally controlled failures are less dominate, and more complex failures such as step-path failures start to develop.
