Slope stability in mining and civil engineering projects is always a problem of great concern. The stability analyses of tetrahedral wedges in rock slopes are commonly conducted using the versatile sequential vectorial operations or stereographic projection methods. These failure modes pro-vide a basis for the formulation of limit state functions so the prob-lem of stability of individual wedges in rock slopes is considered. This mode of failure needs the dip angle of at least one joint intersection to be greater than the angle of friction of the joint surface. The studied mechanism consists of a discrete block that is separated from the rock mass by a tension crack filled with a wedge block or rock fragments. 4). Wedge failure The slope failure occurred along the plane of the soil mass is known as wedge failure.

open pit mining, road cuts, etc.) IS 14448 (1997): Code of practice for reinforcement of rock slopes with plane wedge failure The aim of the investigation is to determine the influence of the main … Wedge Failure Wedge failure, also known as block failure or plane failure, generates a failure plane that is inclined. Because the potential failure was located above a major railroad line, it was necessary to carry out this work with minimal interruption of traffic.

Wedge Failure Wedge failure can occur in rock mass with two or more sets of discontinuities whose lines of intersection are approximately perpendicular to the strike of the slope and dip towards the plane of the slope. We will introduce a few types of slope failure that are common in soils. 0000001383 00000 n An extract from Stability Analysis of Rock Slopes for Plane & Wedge Failure with the Aid of a programmable Pocket Calculator, K. Kovari and P. Fritz, Federal Institute of Technology Zurich, Switzerland Institute of Highways and Underground Structures, Department of Rock Mechanics, 10 pgs. " 0000005398 00000 n Failure of a slope along a weak zone of soil is called a translational slide (Figure 16.2a). This type of failure is commonly seen in slopes of up to 20 or 30 m high in hard jointed rock masses. The key question with regard to rock slopes along highways is their long-term stability since failure of a rock slope can have serious consequences. 110 0 obj<>stream the study of the wedge failure, which occurs as sliding of a mass of rock on two intersecting planes, generally discontinuity planes. %PDF-1.3 %���� Ph.D. Student, Dept. 93 0 obj <> endobj E-mail: Professor, Dept. 0000005774 00000 n ���.�9�rWȅ̦�@�s-��q��(E�P��� E�ä�g��A�10it`� 820�i~ V�(1�1ȰM. 4.
