HUMAN RELIABILITY ANALYSIS IN GEOTECHNICAL RISK ASSESSMENT FOR HILLSIDE DEVELOPMENT

Landslides represent one of the most destructive natural hazards and a major threat in most hillside
development. Over the years, there are little or no concerns on the importance of human factors to be
considered as one of the major causes of landslide. Human Reliability Analysis (HRA) which in turn
has been applied for quite sometimes in other industry sector to assess the human factors contributing
to a risk and identifying proper mitigation measures to reduce the risk can be proposed to adopt into
the geotechnical risk assessment. The needs to focus on the aspect of human factors in geotechnical
engineering is inevitably due to the facts that human interaction interrelated at all stages from planning
to design, and construction to maintenance stages. This paper will review the current state of landslide,
human factors and its influence in Malaysia, introduction of HRA and discusses on the second
generation HRA method known as CREAM.
