Abstract

In 1989 four Reinforced Earth culverts were designed beneath a road embankment located on an alluvial floodplain comprising soft clays and silts. The precast concrete clad sidewalls support deck slabs that in turn carry the road embankment above them. Large settlements were predicted during and particularly after construction. This case history reviews the design, construction and monitoring of the structures. Despite the very much greater than predicted settlements, the structures are performing satisfactorily and have resulted in a cost-effective solution.

Gedurende 1989 is vier Gewapende Grond-kasduikers onder 'n padopvulling op 'n alluviale vloedvlak, wat uit sagte klei en slik bestaan het, ontwerp. Die voorafgegote betonbedekte symure stut die dekblaaie, wat dan die opvulling dra. Groot versakkings gedurende en veral na konstruksie is voorspel. Hierdie gevallestudie kyk na die ontwerp, bou en monitering van die strukture. Alhoewel die versakkings veel groter was as die wat voorspel was, funksioneer die kasduikers bevredigend en het hulle tot 'n koste-effektiewe oplossing gelei.
