This paper presents insights from recent advanced laboratory testing of undisturbed and reconstituted specimens of Christchurch silty-sands. The purpose of the testing was to establish the cyclic strength of silty-sands from sites in the Central Business District (CBD), where liquefaction was observed in 4 September…
Gravelly soil (i.e. gravelly sands, sandy gravels, and uniform gravels) is generally recognized to have no or very low liquefaction potential. However, historically few case histories exist where observations of liquefied gravelly soils have been made, e.g. 1983 Borah Peak, Idaho earthquake (Youd et al….
This paper presents a brief case study investigating the performance of the Kalamata quay wall that exhibited permanent displacement following a Mw 5.9 earthquake. The aim of the investigation was to attempt to predict the observed damage to the wall using available analysis techniques – chiefly simplified analytical…
