Abstract

The geotechnical engineering details of the first of Escom's new generation power stations, with spread footings rather than piles, are described. Of particular significance is the fact that extensive investigation, analysis and resulting design parameters applicable to the major foundation requirements were successfully related to the multitude of remaining foundations without further extensive field work. Remarkably large and deep excavations were undertaken to found the heavily loaded structures successfully, although the overall economy achieved in comparison with normally piled foundations was very rewarding.

Die geotegniese ingenieursbesonderhede van die eerste van Evkom se nuwe geslagkragstasies, met plat fondamente in plaas van helpale, word beskryf. 'n Aspek van besondere betekenis is dat uitgebreide ondersoek, ontleding en die voortspruitende ontwerpparameters, wat op die vernaamste fundasievereistes van toepassing is, suksesvol in verband gebring is met die menigte oorblywende fondamente, sonder verdere uitgebreide veldwerk. Opmerklik groot en diep uitgrawings is onderneem om die swaar belaaide strukture met welslae te fundeer; nogtans was the besuiniging wat teenoor die normale helpaalfondamente bereik is, baie bevredigend.
