DUMBE BYPASS GEOTECHNICAL INVESTIGATION

Transnet Capital Projects appointed us to undertake a geotechnical investigation of the Dumbe bypass on the coal railway line near Paulpietersburg, KwaZulu-Natal.

JG Afrika assessed the embankment and designed remedial measures to repair the damaged section and prevent further failures.

Investigations were undertaken via trial pits and dynamic cone penetrometer tests, in addition to the retrieval of disturbed and undisturbed block samples for specialised tri-axial testing.

The stability of the embankment was analysed and various iterations were undertaken.
