Bukit Lanjan rock slope failure: causal factors and lessons learned

The large scale rock slope failure at the Bukit Lanjan Interchange on the New Klang Valley Expressway has triggered debate amongst road authorities, professionals and the public regarding the degree of safety of cut slopes along major highways in Malaysia. Geological and geotechnical analyses carried out revealed that rock mass properties play an important role in the design and maintenance of rock slopes. Causal factors contributing to failures are complex, however, such factors can be thoroughly investigated and the outcomes used for slope design to minimise public risk. Rock slope re-profiling was selected as a remedial measure of the Bukit Lanjan rock slope failure based on cost considerations, short construction duration, straightforward construction methods, easy access for maintenance, and reduced risk of recurrence of large-scale rock slope failure.
