This MSc in Geotechnical Engineering or equivalent thesis has been submitted for examination with my approval as a thesis advisor. Geotechnical Engineering-II [Lec #26: Slope Stability] 1. This engineer manual (EM) provides guidance for analyzing the static stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. This paper starts by presenting a geotechnical characterization of slope movements that helps in classifying the information related to slopes. Observational,. Variability in Ground Conditions and Site Investigation 3. essential to check the stability of proposed slopes. Slope stability evaluations are concerned with identifying critical With the development of modern method of testing of soils and stability analysis, a safe and economical design of slope is possible.

In this chapter, we will discuss simple methods of slope stability analysis from which one will be able to: Understand the forces and activities that provoke slope failures Understand the effects of seepage on the stability of slopes Estimate the stability of slopes with simple geometry for different types of soils Sloping Face Assessment and Management of Natural Hazards 6 . Assessing the stability of slopes is a difficult task that requires a rigorous approach. A slope is an inclined ground surface which can be either natural or human-made. geotechnical engineering principles and practice. 2010 -04 27 TU Delft SSPC Robert Hack 5 A series of geotechnical studies were performed to analyse slope stability, based on limit equilibrium methods, finite element bidimensional numerical models and discrete element tridimensional numerical model 3DEC. - UET Lahore Email . For infinite slopes that have seepage at the slope face, the factor of safety for slope stability is determined as follows: (7-2) where, . b = the buoyant unit weight of the soil . s = the saturated unit weight of the soil Tan Tan FS Tan Tan FS b Slope Stability Analysis Geotechnical Design Manual M 46-03 Chapter 7-4 December 2006 The main issue is safety against failure; therefore, slope stability analysis consists of calculating the factor of safety. Engineers in this eld are concerned with landslides and other gravity-stimulated mass move-ments. Summary There are two aspects to slope stability: the safety against failure and the movement under normal conditions. For assessments of slope stability, it is important to 1.2 AIMS OF SLOPE STABILITY ANALYSIS In most applications, the primary purpose of slope stability analysis is to contribute to the safe and economic design of excavations, embankments, earth dams, landlls, and spoil heaps. One of the most important parameters influencing the assessment of the stability is the shear resistance that the soil material can mobilize during shearing. This engineer manual (EM) provides guidance for analyzin g the static stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. Fig. . . They are certainly major factors in cut slope stability and in the stability of fill slopes involving both "internal" and "external" slope failures. The geotechnical engineer should have a thorough knowledge of the various methods for checking the stability of slopes and their limitations. Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement. Book Title Stability of Slopes and Underground Excavations Book Subtitle Proceedings of Indian Geotechnical Conference 2020 Volume 3 Editors C. N. V. Satyanarayana Reddy, K. Muthukkumaran, Ravikiran Vaidya Series Title Lecture Notes in Civil Engineering DOI https://doi.org/10.1007/978-981-16-5601-9 Publisher Springer Singapore Slope stability refers to the condition that an inclined slope can withstand its own weight and external forces without experiencing displacement. Decrease in the future of soil or rock mass properties (weathering, vegetation, etc.) As . Other issues include slope monitoring and slope stabilization methods. A slope is an inclined boundary surface between air and the body of an earthwork such as highways, cut or fill, railway cut or fill, earth dams, levees and river training work. 11.2 the line QS represents a plane potential failure surface. Slope stability analysis is a static or dynamic, analytical or empirical method to evaluate the stability of earth and rock-fill dams, embankments, excavated slopes, and natural slopes in soil and rock. Slope stability uses principles of soil/rock mechanics, geotechnical engineering and engineering geology. Geotechnical Risk Management and Risk Communication 2. 11.2 Culmann Aproach to Slope Stability 11.3 CULMANN METHOD A technique for the calculation of slope stability based upon the assumption of a plane surface of failure through the toe of the slope has been proposed by Culmann (see Taylor, 1948). The angle can be negative at the toe. Methods for analysis of slope stability are described and are illustrated by examples in the appendixes. The slope stability analysis is crucial in engineering practice to ensure the stability of structures and prevent loss of human life and money. 6.1 EFFECTS OF WATER ON SLOPE STABILITY Very soft, saturated foundation soils or ground water generally play a prominent role in geotechnical failures in general. Measure (zw)j Calculate where the summation is over the soillayers 35 What causes in-stability of a slope ? The forces acting on the It is concluded that many slope instability hazards may be managed by traditional factor of safety methods, but that it is important that the post failure behaviour be considered. Dept. The discontinues rock slopes or surface cuts are very important concept in geotechnical evaluations which is highly used in road/railway constructions, tunnel engineering, open-pit and underground . Highly significant changes include possibilities for very thorough and detailed evaluations of slope stability and performance, use of 3D stability analyses, finite element and finite . Their job is to frequently evaluate existing and proposed slopes to assess their stability. Methods for analysis of slope stability are described and are illustrated by examples in the appendixes. Limit-state design in Geotechnical Engineering 5. The Geotechnical Manual for Slopes provides guidance for the standards of practice that should be adopted for the design, construction and maintenance of slopes and site formation works in Hong Kong. The eld of slope engineering encompass-es slope stability analysis and design, movement monitoring, and slope safety management and maintenance. A geomechanical assessment is underway to evaluate the stability of the walls for expansion over the next 15 years. Reliability and Risk Analysis of Geotechnical Structures 4. 1992). EVALUATION OF SLOPE STABILITY CONDITIONS BY NUMERICAL ANALYSIS, A CASE OF OTOLO-SAWLA ASPHALT ROAD PROJECT, SOUTHERN PART OF ETHIOPIA . In geotechnical design the material properties are determined rather than specified (Orr & Day, 2002). In Fig. Measure/calculate the angle jatthe base of each slice. Report Title : Geotechnical Manual for Slopes, 2nd Edition (1984), 302 p. (Reprinted, 2011). The paper then shows the tremendous progresses that have recently been made for monitoring slopes, understanding . Class notes of Geotechnical Engineering course I used to teach at UET Lahore.
