REINFORCED EARTH AT NGAURANGA INTERCHANGE, WELLINGTON

A Reinforced Earth Wall retains the approach fill to the southbound overbridge at the Ngauranga Interchange, Wellington. Reinforced Earth was one of three structural alternatives considered and was selected on the basis of cost and anticipated foundation settlement. The wall was designed as a coherent gravity structure using the Ministry of Works and Development's seismic design procedure. The paper describes the design principles used, factors influencing the design, and aspects of the wall's construction including cost. A summary of results obtained through monitoring the wall's performance during construction is presented.
