SAICE Geotechnical Division Evening Lecture 2 (cape Town):

Back to Basics in Geotechnical Engineering – A Lifetime on Dolomite
Presenter: Dr. Fritz Wagener

The presentation will commence with the depositional environment of the mineral Dolomite in shallow seas. The typical profile on dolomite in South Africa and the karst topography of the rock head will follow showing the mechanism of sinkhole and subsidence (doline) formation.

Photographs of major sinkholes since 1962 following dewatering on the FWR to facilitate deep level gold mining will be shown. Methods of construction on dolomite ground will briefly be discussed.
This will be followed by two case histories namely:

  • Sinkholes at Bapsfontein caused by dewatering.
  • A recent major sinkhole at a concrete lined canal conveying water across a dewatered compartment between Carletonville and Welverdiendt on the FWR.

The lecture will be approximately 1.5h long and will be CPD accredited
