2011年3月11日に発生した東北地方太平洋沖地震により,戸建住宅における地盤の液状化に対する対策工法の必要性が社会的に高まりつつある。本論文では,これからの液状化対策のために,液状化の被害を受けた戸建住宅の宅地地盤に焦点を絞り,86地点のスウェーデン式サウンディング試験や三成分コーン(CPT)試験結果をもとに既存の液状化評価手法の検証を行った。また,160件の液状化被害を受けた事例をもとに,地盤補強を実施した戸建住宅の傾斜の状況や傾斜角と補修方法との関連性を整理した。以上の結果をもとに,液状化が生ずるような地盤における適切な地盤補強工法についてその設計の考え方を示した。

The earthquakes of Chuetsu (2004) and Chuetsu offshore (2007) in Niigata Prefecture caused frequent slope failures, landslides and ground liquefaction, and numerous instances of ground-induced damage to houses and residential areas were noted. In many cases, damage from liquefaction occurred not only on reclaimed land in coastal areas but also on residential areas where river channels had been filled. This research investigates the characteristics and propensities of liquefaction damage to houses and residential areas. Case histories of damage are analyzed, and the current state of aseismic capacity evaluations of residential areas in Japan and future issues are reported.

The earthquakes of Chuetsu (2004) and Chuetsu offshore (2007) in Niigata Prefecture, caused liquefaction at many locations, and also caused damages on the residences and the residential areas due to the failure of ground. In the future, the judgment of liquefaction on housing site will become important and it will be thought that the upgrade of soil investigation and liquefaction countermeasure is necessary. In Japan, Swedish weight sounding (SWS) has been widely used in soil investigation on residential areas. Based on the result of SWS, the bearing capacity of ground can be obtained. However, the judgment of liquefaction is not obtained. This paper reports results of SWS, boring investigation, standard penetration test (SPT), and three component cone penetration test (CPT) on the housing site which caught the liquefaction damage by the earthquake of Chuetsu offshore (2007) in Niigata Prefecture. In addition, it reports the applicability of the CPT on the housing site of Japan. Copyright© 2008 by The International Society of Offshore and Polar Engineers (ISOPE).

... The relation stated by Inada [9], subject to various kinds of modifications [18], [37], [34], has been used for interpreta-tion of results since the early 1960's. The probe was used, among others, in Turkey [34], Iran [7], [31], India [32], Sumatra [17] and Japan [13], [15], [28], [33], [35], and more recently in New Zealand, in conjunction with the strong earthquake which struck the country in 2010 [2], [3], [29], [36]. Despite the fact that the probe has already been in use for almost 100 years, no standard data interpretation rules have been developed so far (except for a small group of non-cohesive soils) [25]. ...
