Geotechnical Risk Assessment
12
Flashcards
0/12
Uncertainty Analysis
The study of uncertainty sources within risk assessment and their potential impact. Involves statistical techniques such as Monte Carlo simulations.
Hazard Identification
The process of recognizing that a hazard exists and defining its characteristics. Performed by site inspection, historic data analysis, and consultation with experts.
Risk Communication
The exchange of information about risk among decision-makers, stakeholders, and the public. Essential for the transparent decision-making process.
Quantitative Risk Assessment
Objective assessment of risk using numerical values for probabilities and magnitude of impact. Utilizes statistical data and mathematical modelling.
Soil Liquefaction Assessment
Evaluating the risk and potential consequences of soil liquefaction during seismic events. Performed using field tests like SPT, CPT, and analysis of geological conditions.
Geotechnical Monitoring
Periodic or continuous surveillance of geotechnical conditions through instruments and site inspections to manage risk associated with ground conditions.
Qualitative Risk Assessment
Subjective assessment of risk using descriptive terms or categories. Method includes expert opinions and comparative risk ranking.
Slope Stability Analysis
The assessment of the safety of earth slopes and the potential for landslides. Involves the use of stability charts, limit equilibrium methods, and numerical modeling.
Risk Analysis
Determining the nature and level of risks by analyzing potential hazards and evaluating existing conditions of vulnerability. Uses probabilistic models and reliability analysis.
Foundation Risk Management
The identification, analysis, and response planning for risks associated with foundation construction. Involves load tests, soil investigations, and construction monitoring.
Risk Management
The process of making and carrying out decisions that will minimize the impact of risk on an organization. Involves risk analysis, risk assessment, and mitigation strategies.
Mitigation Measures
Strategies and actions implemented to reduce or eliminate risks associated with geotechnical engineering. These include reinforcement, grouting, and drainage systems among others.
