The Use of Cement Stabilised Marine Mud in Breast Works for the Ports of Auckland : (S.J. Priestley)
Redevelopment of the eastern section of the Viaduct Basin in downtown Auckland provided the stopover base for the 1993/1994 Whitbread Race. This required the construction of a new quay structure, dredging and a reclamation. An integral part of the whole project was the use of cement stabilised marine mud (mudcrete) for the reclamation. This paper discusses the design methodology for the sizing of the structural elements in the quay wall and outlines the benefits of using mudcrete. Also the paper outlines the investigations undertaken to assess the effects of leachate release from the reclamation to the natural environment.
Suggestions for Geotechnical Ultimate Limit State Design : ( M.J. Pender, R.G. Andersen)
Limit State Design is a general term embracing many different procedures. The purpose of the method is (1.) to deal with sources of uncertainty affecting the design, and (2.) to differentiate between situations leading to collapse of a structure (ultimate Limit State) from those in which the limit state is unacceptable deformation ( serviceability Limit State). For both classes of limit state it is presumed the designer has investigated a sufficient number of scenarios to identify the most critical case which comes the basis of design. The particular feature of limit state design is the separation of the uncertainties associated with the loads from those associated with material properties. In the traditional approach these are lumped together in a single factor of safety. The intention of this paper is to promote discussion of procedures for the ultimate limit state geotechnical design in New Zealand.
