ABSTRACT Tremie concrete enables the construction of deep foundations such as piles and diaphragm walls as it is self-compacting, can be placed under a support fluid and is resistant to segregation. As the urban landscape within New Zealand increases in density, deeper and more complex…
ABSTRACT This paper provides investigation into response of (forward-rotated or backrotated) piles subjected to embankment loading, in light of 2-/3-layer models. First, recent advance is briefly reviewed concerning range of parameters used to model piles subjected to excavation and embankment loading. Second, simulations of six…
ABSTRACT In 2011, rockfalls made Sumner Road near Christchurch unsafe and the road was closed to all traffic. This 2.5 km-long Christchurch City Council operated road, an important alternative route to the Lyttelton Tunnel, sustained extensive damage due to rockfall and retaining wall failures during…
ABSTRACT South Dunedin is located on a small coastal plain that has formed over a drowned and subsequently infilled valley. Formerly a salt marsh formed behind sand dunes, South Dunedin has been progressively developed since 1840 and is now one of the most-densely populated…
ABSTRACT This paper compares the predicted and observed construction-induced settlement for a project in Hamilton, N.Z. The project involved the construction of four shafts and associated pipelines in high-permeability alluvial (Hinuera) soils in an area with a high water-table. The city is embarking on significant…
ABSTRACT Within an 18 month period the Tairāwhiti region was hit with 3 heavy rainfall events and 2 cyclones. This resulted in over 5,200 recorded road faults across its 2,238 km network. The extent of the damage at any site ranged from minor culvert blockages…
ABSTRACT Rock slopes in most mining areas are prone to instability, because of the rock mass conditions are strongly effected by both internal rock properties and external conditions. Therefore, instability of rock slope attracts a high level importance for researchers, especially in the conventional…
ABSTRACT The Cutter Soil Mixing (CSM) method was used for in-situ mixing of contaminated reclaim ground at Wynyard Point, in the waterfront area of Auckland, to facilitate the installation of a large diameter outfall pipeline. A soil/cement block was formed by the CSM working…
ABSTRACT Trees in urban environments cool cities, capture carbon, and reduce stormwater runoff through enhanced initial losses. However, their root systems require uncompacted soil to grow, a requirement that is inconsistent with optimal pavement performance. To accommodate trees in roadways, carparks and pedestrian accessways, Citygreen…
ABSTRACT The current SH1 alignment at Bulli Point follows the eastern margin of Lake Taupo and is situated directly above the lake at the toe of a sharp ridge. The site has a history of low speed crashes due to an ignimbrite bluff overhanging…
