oa Civil Engineer in South Africa - Upgrading of the coal line between Piet Retief and Paulpietersburg

 

Abstract

This paper describes the design of two deviations for improvements to the coal line between Piet Retief (in the eastern Transvaal) and Paulpietersburg (in northern Natal), which comprise a total length of approximately 42 km of new double track formation. The location of the route between fixed points on the existing line, through rugged terrain, is outlined and the route geology is described in brief. An insight is given into the design philosophy applied to the stability design of batter slope inclinations for cuttings up to 40 m deep and embankments up to 40 m high, with insitu materials varying from deep alluvial deposits to outcrops of solid competent rock. The application of some new methods and ideas to ensure stability are described, and an indication is given of the extent of the associated bridges and drainage structures.

Hierdie referaat beskryf die ontwerp van twee verleggings vir verbeterings van die steenkoollyn tussen Piet Retief (in die oos Transvaal) en Paulpietersburg (in noord Natal), en behels in totaal, 'n lengte van ongeveer 42 km nuwe dubbellyn formasie. Die roetebepaling tussen vasgestelde punte op die bestaande lyn, deur moeilike terrein, is kortliks bespreek en die geologie van die roete word beskryf. 'n Insig word gegee aangaande die ontwerp filosofie toegepas in die stabiliteitsontwerp van syhellings vir deurgrawings tot 40 m diep en opvullings tot 40 m hoog met materiaal wat varieer van diep alluviale afsetting tot soliede harde rots, en die toepassing van nuwe metodes en idees om stabiliteit te verseker word bespreek. 'n Aanduiding word gegee van die omvang van die bykornende brüe en dreinerings strukture.
