A Study on the Contributing Factors of Major Landslides in Malaysia
Abstract: Landslide is one of
the most prominent geo-hazard that accounts for colossal losses every year. The
contributing factors of landslides in Malaysia are reasonably different from
rest of the world. According to a study, the most dominant factor that
catalysis the slope failure in many countries of the world is geological
conditions. However, in case of Malaysia; most of the landslides occur as a
consequence of flawed design, improper construction and non-maintenance of
slopes which correlates with the human errors. The statistics of Malaysia shows
that highest number of landslides took place in 1996 with 71 cases which is
followed by 68 cases in 1995. According to the findings of Highland Towers
(1993) landslide, the main causes of failure were inaccuracies in design, poor
supervision during the construction and inadequate drainage system. Similarly,
in case of Taman Hillview and Bukit Antarabangsa landslide, it has been
revealed that improper design practices and poor drainage system supplemented
with prolonged rain were the significant causes of the cataclysm. Therefore,
based on the investigations on retrospective landslides, this study proposes to
incorporate Human Reliability Assessment technique as a part of working
strategy for slopes along with strong adherence to the design guidelines in
order to minimize the likelihood of landslides.
