Performance of earthworks infrastructure

The performance and behaviour of earthworks (cuts, fills and retaining structures) impacted by landslides generated by the 2016 Mw 7.8 Kaikoura earthquake have been investigated by WSP consultants. The work, presented in four reports, provides case studies and recommendations for resilient design and construction of these earthworks. The first report provides maps and summarises the […]
