Quantitative Risk Assessment QRA "Slope Safety" is a long-term programme of sustained effort on all fronts to achieve the quickest possible reduction in landslide risk to the community in Hong Kong.
The use of Quantitative Risk Assessment QRA technique in evaluating and managing landslide risk is gradually becoming recognized by the geotechnical practitioners in Hong Kong. This has led to a number of developments and applications of the technique to landslide problems in recent years.
This web page provides a brief summary of the basic risk concepts and some pilot applications of QRA to geotechnical problems in Hong Kong.
The creation of this web page is to facilitate the promulgation of pilot development work and the findings of these studies. Basic Concepts Terminology Acceptable Risk: A risk for which, for the purposes of life or work, society is prepared to accept as it is with no regard to its management.
ALARP as low as reasonably practicable: The risk is regarded as tolerable only if risk reduction is impracticable or if the cost is grossly disproportionate to the improvement gained. This involves determining HSE, The injunction laid down in safety law is that any risk must be reduced so far as reasonably practicable, or to a level which is 'as low as reasonably practicable'.
Meaning the population, buildings and engineering works, economic activities, public services utilities and infrastructure in the area potentially affected by landslides IUGS Working Group on Landslides, A technique, which can be either qualitative or quantitative, used to identify the possible outcomes and, if required, their probabilities, given the occurrence of an initiating event CSA, A technique, which can be either qualitative or quantitative, by which conditions and factors that can contribute to a specified undesired event called the top event are deductively identified, organized in a logical manner and represented pictorially BSI, A physical situation with the potential for causing an undesirable consequence.
Descriptions of landslide hazard, particularly for zoning purpose, should include the characteristics of the landslides, which may include the volumes or areas of the landslides and the probability of their occurrence. There may also be value in describing the velocities, and differential velocities of the landslide.
The recognition that a hazard exists and the definition of its characteristics CSA, The likelihood of a specific outcome, measured by the ratio of specific outcomes to the total number of possible outcomes.
Probability is expressed as a number between 0 and 1, with 0 indicating an impossible outcome, and 1 indicating that an outcome is certain IUGS Working Group on Landslides, A measure of the probability and severity of an adverse effect to health, property, or the environment. It is often estimated by the product of probability and consequences.
However, a more general interpretation of risk involves probability and consequences in a non-product form. The use of available information to estimate the risk to individuals or populations, property or the environment, from hazards.
Risk analyses generally contain the following steps: The process of decision-making for managing risk, and the implementation, enforcement, and re-evaluation of its effectiveness from time to time, using the results of risk assessment as one input CSA, A qualitative and quantitative statement of the acceptable standard of risk with which the assessed risk needs to be compared Royal Society, Risk Estimation: The process used to produce a measure of the level of health, property, or environmental risks being analysed.
Risk estimation contains the following steps: The stage at which values and judgements enter the decision process, explicitly or implicitly, by including consideration of the importance of the estimated risks and the associated social, environmental, and economic consequences, in order to identify a range of alternatives for managing the risks CSA, ; IUGS Working Group on Landslides, The risk of multiple injuries or deaths to society as a whole: A bounded, physical entity that achieves in its environment a defined objective through interaction of its part.
This definition implies that a the system is identifiable, b the system is made up of interacting parts or subsystems, c all the parts must be identifiable, and d the boundary of the system can be identified CSA, A risk that society is willing to live with so as to secure certain net benefits in the confidence that it is being properly controlled, kept under review and further reduced as and when possible IUGS Working Group on Landslides, The selected outcome whose possible causes are analyzed in a fault tree Jones, The degree of loss to a given element or set of elements within the area affected by the landslide s.
It is expressed on a scale of 0 no loss to 1 total loss. For property, the loss will be the value of the property; for persons, it will be the probability that a particular life the element at risk will be lost, given the person is affected by the landslide IUGS Working Group on Landslides, Risk Management - Part 3: Risk Analysis Requirements and Guidelines.
