Stability of Slopes Introduction. 2. "Stability Analysis Of Rock Slopes For Plane And Wedge Failure With The Aid Of A Programmable Pocket Calculator." The basic formula may in both cases also be used to make a detailed parametric study to investigate the sensitivity of the rock slope construction to variations in individual parameters. Summary. Die Aufdeckung einer formalen Analogie zwischen dem Abgleiten auf einer Ebene und dem Abgleiten eines Felskeiles auf zwei Ebenen erlaubt es, die einfache Grundformel des ebenen Problems direkt für die Lösung des verwickelten räumlichen Problems anzuwenden. non-associative character of toppling-sliding rock slope failures, examples of experimental data were chosen from the rock mech-anics literature to address (iii). 5.1Example 1 – plane failure of slope with daylighting discontinuities The first example involves a set of discontinuities spaced 10m apart, which dip out of the slope at 35° (see Figures 2a to 2c).

For highly fractured rock, the original HB failure criterion has been modified, but its effect on the stability of rock slopes has not been studied. These slopes often include open-pit mining, embankments, road cuts, landfills, and excavations. Plane failure analysis The potentially unstable regions in rock slopes consist of some wedges. 3 could be used as a set of reference curves: that is, the appropriate curves could be traced to obtain the daylight envelope required for slope stability analysis. Ceci permet d'appliquer directement la formule fondamentale, du problème plan, qui est simple, à la résolution du problème enchevêtré qui se présente dans l'espace. Slope failures in the quarry are controlled by rock structure. Failure of a rock slope on one or two plane surfaces is the simplest but at the same time the most important type of sliding failure and forms the basis for the stability analysis of rock slopes. volume 13, pages105–111(1995)Cite this article. The limit equilibrium method is generally utilized in the stability analysis of rock slope with single failure plane. 27 3.2 Anchored rock … Tax calculation will be finalised during checkout. Geotech Geol Eng 13, 105–111 (1995). (1981) Rock Slope Engineering, The Institution of Mining and Metallurgy, London. (a) Plane, (b) wedge, (c) circular and (d) toppling -sliding. This investigation may be carried out quickly, without time consuming calculations, even at the site, if a programmable pocket electronic calculator is available. You could not be signed in. At the time of failure, the shear strength of the soil is fully mobilized along the failure plane. Learn more about Institutional subscriptions. ROCK SLOPES PROCESSES AND RECOMMENDED METHODS FOR ANALYSIS A. K. Alzo'ubi College of Engineering, Abu Dhabi University, UAE ABSTRACT: The stability of rock slopes is of great concern in many engineering projects, for example, road cuts, foundations, retaining walls, and dam excavation Generally, rock slopes susceptible to instability could be divided into two main categories, the … Kinematic Analysis – Planar Rock Slope Failure To consider the kinematic admissibility of plane instability, five necessary but simple geometrical criteria must be met: (i) The plane on which sliding occurs must strike near parallel to the slope face (within approx. Failure could arise from a single discontinuity, a pair of … Subscription will auto renew annually. Vancouver, 2016, 77–90: 11: G Liu, X Zhuang, Z Cui. The orientation and spacing of the discontinuities plane with respect to the slope face are the determinants of rock slope failure. Kinematic Analysis Kinematic Analysis –– Planar Rock Slope FailurePlanar Rock Slope Failure To consider the kinematic admissibility of plane instability To consider the kinematic admissibility of plane instability, five necessary but simple geometrical criteria must be met: (i) The plane … The most important types of slope failure are illustrated in Fig.1. The application of Goodman and Bray's limit equilibrium analysis of multi-block toppling failures to these three slopes is demonstrated. Dans cet exposé figure un programme complet pour le modèle très répandu: le "Hewlett-Packard HP-65". Despite the simplicity of the mathematical model, the necessary computations using present methods are time consuming on account of the large number of parameters entering into the computations (geometrical parameters, material properties, anchor forces etc.) Anhand einiger Beispiele wird die Anwendung auf praktische Fälle des Felsbaues illustriert. The original Hoek-Brown (HB) failure criterion was used to analyse the stability of rock slopes. A simple formula for plane slope failure is derived, which may be used for the design of anchors to ensure the safety of rock masses endangered by slides. bridge along the sliding surface in the plane failure and wedge failure analysis. This is a preview of subscription content, log in to check access. These methods are developed on the assumption that the plane of failure is circular arc, apart from the Culmann method that assumes a plane surface of failure through the toe of the slope. Summary A simple formula for plane slope failure is derived, which may be used for the design of … In this manner the engineer can obtain a good idea of the sensitivity of the rock slope construction to changes in the individual parameters. An analysis is presented here which can take these factors into account.
