“…Ishihara and Okata [3] also found that the stress-induced anisotropy developed by preshearing can greatly influence the rate of increase in the pore pressure during liquefaction. This finding has been confirmed by other studies [4][5][6]. Recently, Yamada et al [7] and Ye et al [8,9] showed experimentally and theoretically that the pre-shearing induced by liquefaction can cause continuous, orderly and rapid changes in anisotropy, which then influences the reliquefaction resistance of sand during future loadings.…”

“…First, it can be verified that the definition of small and large pre-shearing adopted in the present study satisfies the criterion generally introduced in literature by other authors (Ishihara and Okada 1978, 1982, Suzuki and Toki 1984. According to this criterion the phase transformation line obtained from monotonic tests (PTL mon ) can be considered as a boundary line separating the two different domains.…”

“…The concept of 'phase transformation state' can be used in sands characterised by a dilative-type response to match a boundary limit between small and large pre-shearing (Ishihara and Okada 1978, 1982, Suzuki and Toki 1984.…”

The paper will offer insights regarding the effects of cyclic prestrain history on the undrained behaviour of an uncemented carbonate sand (Quiou sand) through a modified NGI simple shear (SS) apparatus. Tests were carried out on specimens reconstituted at two void ratios (loose and dense) by using the water sedimentation method. The influence of cyclic undrained pre-shearing was investigated by applying both small and large limiting shear strains; after reconsolidation, the specimens were again subjected to the same cyclic phase as before, until the sample liquefied. The pattern of postcyclic behaviour of the tested sand showed the relevant role assumed by the phase transformation line obtained from monotonic tests on virgin specimens. For both loose and dense specimens a threshold value of cyclically induced pre-shear strain was found at which the positive effect of previous cyclic loading history on liquefaction resistance disappears or starts to reverse. A normalising criterion, capable of providing a unified description of the pore-pressure build-up curves for different pre-shearing histories, was verified. Finally, a direct comparison between the tested sand and a silica sand with similar grain size features was also presented in order to ascertain the influence of particle crushing on the post-cyclic liquefaction behaviour.

“…By applying many numbers of cyclic shear with small strain amplitude, it has been shown that liquefaction resistance increases (Suzuki and Toki, 1984;Wichtmann et al, 2005;Kiyota et al, 2010). Although ageing-like phenomena have been mimicked in laboratory tests (e.g., mixing with cement or running preshearing), noteworthy from the practical viewpoint is that it is difficult to predict the temporal rate of insitu ageing.…”

The present text is a summary of liquefaction events that occurred in the Kanto Region during the 2011 off the Pacific coast of Tohoku Earthquake, excluding those events in the Tokyo Bay area that are discussed elsewhere. Most liquefaction occurred in the abandoned river channels and former lakes that had been recently filled with liquefiable soils. Noteworthy was the damage to private housing lands and river dikes that had not been well treated against liquefaction risk. Many sites experienced repeated liquefaction after former earthquakes in 1923 or 1987, if they existed in those times. In contrast to the recent liquefaction-prone soils, more-aged sands scarcely liquefied because of what is called the "ageing" effect. The present study analyzed cases in Tokyo area to quantitatively assess the temporal development of ageing so that liquefaction risk in more aged soils might be reasonably assessed. In the appendix, remarks are made of the reliability of air-photo survey in quick detection of liquefaction sites.
