REMEDIAL MEASURES FOR SLOPE INSTABILITY

ABSTRACT

In Malaysia, there have been numerous occurrences of embankment and cut slope failure in recently completed earthwork. In addition, serious environment damage is being and has been caused to streams and rivers as a result of uncontrolled soil erosion from ongoing or recently completed earthworks in development projects. These problem are particularly acute because of the climate, which produces intense and prolonged rainfall during the monsoon periods, because of the steep mountains terrain and also because of the common occurrence of highly and completely weathered rocks and residual soils, which are particularly susceptible to erosion. The challenge of preventing these problems and of maintaining earthwork stability, both during and immediately after the construction period and also on the long term, requires a considerable application of engineering expertise, more stringent application of know, good construction practices and further research into engineering methods for specific Malaysia problem.

The tragic collapse of the Highland Tower Apartment in Hulu Kelang Selangor has triggered a sudden awareness on the need for some government regulation concerning hillside development in particular and high density building in general. Geotechnical and environmental assessments are being imposed by the government for all current and future projects. All developers of highrise buildings especially on hill slopes are require to submit to the local authorities finding and recommendations of independent engineering assessors of their present projects.
