HUMAN ERROR RELATED RISKS OF MALAYSIAN LANDSLIDES
This paper discusses landslide risks. Rainfall is not always the major contributing factor at every landslide. Most of the times the actual root causes are engineering (e.g. flaws in slope design, errors during construction etc.) or non engineering activities (e.g. deforestation, poor vegetation c...

| Summary: | This paper discusses landslide risks. Rainfall is not always the major contributing factor at every
landslide. Most of the times the actual root causes are engineering (e.g. flaws in slope design, errors
during construction etc.) or non engineering activities (e.g. deforestation, poor vegetation cover, poor
maintenance etc.). In both cases contributions of humans error to failure exists. In this paper landslide
failure probabilities due to human errors have been estimated using fault tree analysis (FTA). Human
errors are classified on the basis of design, construction and maintenance errors. Consequences of
failure are the second basic parameter used to evaluate risks but in this study on the basis of
probability of failure level of risk has been estimated. Level of risk is dependent upon the intensity of
human errors involved in subtask items of design construction and maintenance. As conclusions the
study furnishes probability of failure of those subtasks which are highly under the influence of human
errors. |
