Geotechnical engineering aspects of Matimba Power Station

The geotechnical engineering details of the first of Escom's new generation power stations, with spread footings rather than piles, are descriptionbed. Of particular significance Is the fact that extensive investigation, analysis and resulting design parameters applicable to the major foundation requirements were succeaafully 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.
