Assessing and managing instability hazards in open pit mines are the essential activity when working with the natural and engineering slopes, due to its potentiality for loss of life and property. The slope stability radar (SSR) is an all-weather system that remotely scans wall of the slopes to measure the slope surface movement with sub-millimeter precision. It allows user to detect and alert personnel of rock movements that result in instability.

What is SLOPE STABILITY ANALYSIS? What does SLOPE STABILITY ANALYSIS mean? SLOPE STABILITY ANALYSIS meaning - SLOPE STABILITY ANALYSIS definition - SLOPE STABILITY ANALYSIS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Slope stability analysis is performed to assess the safe design of a human-made or natural slopes (e.g. embankments, road cuts, open-pit mining, excavations, landfills etc.) and the equilibrium conditions. Slope stability is the resistance of inclined surface to failure by sliding or collapsing. The main objectives of slope stability analysis are finding endangered areas, investigation of potential failure mechanisms, determination of the slope sensitivity to different triggering mechanisms, designing of optimal slopes with regard to safety, reliability and economics, designing possible remedial measures, e.g. barriers and stabilization. Successful design of the slope requires geological information and site characteristics, e.g. properties of soil/rock mass, slope geometry, groundwater conditions, alternation of materials by faulting, joint or discontinuity systems, movements and tension in joints, earthquake activity etc. The presence of water has a detrimental effect on slope stability. Water pressure acting in the pore spaces, fractures or other discontinuities in the materials that make up the pit slope will reduce the strength of those materials. Choice of correct analysis technique depends on both site conditions and the potential mode of failure, with careful consideration being given to the varying strengths, weaknesses and limitations inherent in each methodology. Before the computer age stability analysis was performed graphically or by using a hand-held calculator. Today engineers have a lot of possibilities to use analysis software, ranges from simple limit equilibrium techniques through to computational limit analysis approaches (e.g. Finite element limit analysis, Discontinuity layout optimization) to complex and sophisticated numerical solutions (finite-/distinct-element codes). The engineer must fully understand limitations of each technique. For example, limit equilibrium is most commonly used and simple solution method, but it can become inadequate if the slope fails by complex mechanisms (e.g. internal deformation and brittle fracture, progressive creep, liquefaction of weaker soil layers, etc.). In these cases more sophisticated numerical modelling techniques should be utilised. Also, even for very simple slopes, the results obtained with typical limit equilibrium methods currently in use (Bishop, Spencer, etc.) may differ considerably. In addition, the use of the risk assessment concept is increasing today. Risk assessment is concerned with both the consequence of slope failure and the probability of failure (both require an understanding of the failure mechanism). Within the last decade (2003) Slope Stability Radar has been developed to remotely scan a rock slope to monitor the spatial deformation of the face. Small movements of a rough wall can be detected with sub-millimeter accuracy by using interferometry techniques.

Although the footage lasted only a few minutes, it is horribly exciting enough. I hope that this video can let you all appreciate the consequence of ruining our environment." 当年，我接到一名锡矿矿主的电话，说他经营几十年的矿场就要土崩堤解，我即刻拿起录影机火速赶到现场，苦等了几个小时，终于，让我拍到珍贵的镜头。虽然只有短短几分钟的录相片短，但足让旁观者心跳一百，希望这套短 片能让各界的朋友反思环境遭破坏的后果。

This webinar demonstrates the application of the new Multi-Plane Analysis (MPA) technology implemented in the SVSLOPE 2D MINING edition of our software. Traditional analysis of earth dams involve a complicated process of pulling and organizing specific cross-sections out of AutoCAD geometry. The process for geotechnical engineers is complicated and time consuming. The methodology also raises questions such as "What if the slice chosen is slightly different? Does it greatly affect the calculated factor of safety?". The MPA analysis allows the user to set up complex geometries and analyze a small or large batch of 2D slicing planes. The site can be fully set up in our SVDESIGNER software package. Then the geometry can be transferred to SVSLOPE to set up tens, hundreds or thousands of slicing planes where each plane is a fully formed 2D limit equilibrium slope stability models. The results of the analysis are then compiled by the software and may be visualized over top of the original 3D conceptual model. Such technology is perfect for the 2D analysis of complex earth structures. This webinar will focus on the application to the analysis of tailings dams. Such analysis has the potential to more fully analyze the effects of 3D geometry on the related factor of safety for such earth structures. The presentation includes a brief overview of the MPA methodology, a demonstration of a simple application, and then a demonstration of a more real-world type of site.

2017 H. Bolton Seed Medal Lecture: Numerical Analysis of Stability and Risk in Highly Variable Soils D. Vaughan Griffiths Ph.D., P.E., D.GE, F.ASCE, Colorado School of Mines There has been a rapid growth of interest in risk assessment, and the use of probabilistic methods in geotechnical engineering. This is a logical development, since soils and rocks are among the most variable of all engineering materials, and geotechnical engineers must often make do with materials they are dealt with at any particular site. Analysis of a typical stability problem may lead to a “probability of failure”, as opposed to the more traditional “factor of safety”, representing a fundamental shift in the way engineers need to think about the suitability of their designs. The lecture will include results of stability analyses of variable soils by the finite element method, and include a discussion of the factor of safety and its relationship to the probability of failure. Some methods of probabilistic analysis with varying levels of complexity will be described. The H. Bolton Seed Medal Lecture is given annually by the recipient of the H. Bolton Seed Medal for outstanding contributions to teaching, research or practice in geotechnical engineering. BIO: Dr. Griffiths was selected by the Geo-Institute Board of Governors to receive the 2017 H. Bolton Seed Medal “For his innovative software developments, publications, textbooks and professional short courses on finite elements and probabilistic methods. His highly-cited work on finite element stability analysis has transformed the way engineers perform slope stability analysis in practice.” In selecting him for this award, the committee particularly noted his reputation as a pioneer in numerical modeling.

2017 Ralph B. Peck Medal Lecture: A New Paradigm for Slope Stability Analysis under Variably Saturated Conditions Ning Lu Ph.D., F.EMI, F.ASCE, Colorado School of Mines This lecture will highlight two major advancements in slope stability analysis that stemmed from several multi-year field hydro-mechanical monitoring. The first significant breakthrough is the capability to handle the transient field of effective stress in variably saturated slopes under rainfall conditions. Using effective stress analysis preserves the rigor, simplicity, and practicality of the classical slope stability methodologies (e.g., limit equilibrium). The second is to quantify the field of local factor of safety (FS), which radically departs from the classical one-FS-for-one-slope paradigm and allows identification of failure initiation and progression zones in slopes. The new hydro-mechanical framework for slope stability design and analysis only requires three parameters in addition to the classical shear strength and seepage parameters. These parameters are used to uniquely define slope materials’ constitutive relations of the soil water characteristic curve, hydraulic conductivity function, and suction stress characteristic curve. Several field cases are used to illustrate the validity, accuracy and simplicity of the new hydro-mechanical framework for slope stability analysis. The Ralph B. Peck Medal Lecture is delivered annually by a geotechnical engineer selected for outstanding contributions to the profession through the analysis and publication of case histories. BIO: Dr. Lu was selected by the Geo-Institute Board of Governors to receive the 2017 Ralph B. Peck Award “For his multi-year case study monitoring the subsurface hydrological and mechanical conditions leading to landslide occurrence on the coastal bluffs between Seattle and Everett, WA, and using the data collected to develop a new hydro-mechanical framework for slope-stability analysis.” In selecting him for this award, the committee particularly noted his body of research on rainfall-induced land sliding.
