Oct 04, 2007· a preliminary method would be Romana''s Slope Mass Rating (SMR), I applied it in situations similar to yours (albeit in smaller faces) with good results. Also, Rocscience ''s Roclab, freeware, gives out a max height for a vertical face given a visual comparison to rock mass classes (GSI method, an evolution of Bjieniawski''s RMR).

Based on field observations, the slope angle in the area is dominated by steep slopes. The rock hardness level is dominated by hard rock with a hardness ranging from 50100 MPa. Rock Mass Rating shows that the are a is dominated by good rocks. While the S lope Mass Rating calculation show that the maximum slope angle is between 5275 ° .

The aim of this study is to investigate slope stability problems for heavily jointed karstic limestones in an aggregate quarry. Limestone quarries have turned into steep cliffs of bare rocks which threaten the safety of construction and have also negative influence on the aesthetics in the Cebeci Region.

Limestone quarries have turned into steep cliffs of bare rocks which threaten the safety of construction and have also negative influence on the aesthetics in the Cebeci Region.
At present, the research on the stability of the high cut slope mainly focuses on the longterm safety and stability of the rock slope caused by unloading after the excavation of the rock mass [1–3]. However, the dynamic stability analysis of the slope under the action of blasting load is still in the exploration stage, and there is still a ...
SLOPE STABILITY 1. Purpose. This engineer manual (EM) provides guidance for analyzing the static stability of slopes of earth and rockfill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. Methods for analysis of slope stability are described and are illustrated by examples in the appendixes.
Design of Rock Slopes SHA ILER S. PHILBRICK, Office of District Engineer, U. S. Corps of Engineers, Pittsburgh, Pa. The design of rock slopes is discussed in this paper much as if an actual cut slope in rock were being designed. First, the en gineering requirements of the cut; second, the geologic condi

Stability analysis of a rock slope requires assessment of shear strength parameters, that is, cohesion (c) and angle of internal friction of the rock mass. Dilatancy in a rock mass is unconstrained near slopes as normal stress on joints is small due to weight of the wedge.
ascertain the degree of slope stability. Discontinuity orientations in the rock mass were mapped using compass clinometers. Kinematic analyses of the discontinuities were carried out using DIPS software. The results of the investigation revealed evidence of potential slope failures from the two joint sets identified in the study area.

Slope stability is the process of calculating and assessing how much stress a particular slope can manage before failing. Examples of common slopes include roads for commercial use, dams, excavated slopes, and soft rock trails in reservoirs, forests, and parks. Considering the importance of slope stability to their work, it''s beneficial for civil engineers to understand how to
Abstract. The Cebeci Region is characterised by famous outcrops of Carboniferous Limestone which is mined out for aggregate production. The aim of this study is to investigate slope stability problems for heavily jointed karstic limestones in an aggregate quarry.
EFFECTS OF WATER ON SLOPE STABILITY Very soft, saturated foundation soils or ground water generally play a prominent role in geotechnical failures in general. They are certainly major factors in cut slope stability and in the stability of fill slopes involving both "internal" and "external" slope .
