oa Civil Engineer in South Africa - A classification system for excavation in natural materials

 

Abstract

A classification system is proposed which is based on the relevant engineering properties of the ground and which does not allow the method of excavation to dictate the class of excavation. The system provides for the classification of the complete range of materials from the weakest soils to the hardest rocks irrespective of the size, shape or means of excavation. Provision is made to determine the excavation class quickly by means of empirical assessments. To obviate disputes,provision is further made to determine the input parameters quantitatively by standard tests. Some of the currently used classification criteria are briefly reviewed.

'n Klassifikasiesisteem gebasseer op toepaslike grondparameters en wat nie die metode van uitgrawing die uitgrawingsklas laat voorskryf nie, word voorgestel. Die sisteem maak voorsiening vir die klassifikasie van materiale oor die totale spektrum van sagte grond tot harde klip ongeag die grootte, vorm en wyse van uitgrawing. Voorsiening word gemaak om die uitgrawingsklas vinnig te bepaal met behulp van empiriese waarnemings. Om geskille te vermy word voorsiening ook gemaak om die insetparameters kwantitatief met behulp van standaard toetse te bepaal. Sommige van die huidige klassifikasie-norme word kortliks bespreek.
