PECULIARITIES OF LIQUEFACTION RESISTANCE OF MASADO
Doboku Gakkai Ronbunshu, 2000 本研究は, まさ土の液状化抵抗の特殊性を粒径のそろった“きれいな砂”である豊浦砂との対比で検討したものである. 液状化抵抗を表す指標としては, 非排水条件下での定ひずみ振幅ステップ載荷試験から得られる累積損失エネルギー量を用いている. 著者らによって提案されている同指標は, 地盤材料の靭性を考慮できる液状化抵抗の評価指標である. まさ土の液状化抵抗に影響を及ぼす要因として細粒分の存在と破砕性の影響を検討した. 更に, 埋立て材料としての観点から, 締固めによる液状化抵抗の改善効果も評価した.一連の繰返しせん断試験結果からまさ土の液状化抵抗が豊浦砂に比べて密度依存性が小さいこと, 粗粒分の土粒子に付着した細粒分が液状化抵抗に重要な役割を果たしていることを明らかにした.

Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]
, 2009 In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).

Liquefaction analysis of abrasion protection structure in Padang
MATEC Web of Conferences, 2018 The liquefaction potential of a soil deposit is an important aspect to consider the stability of structure due to the earthquake. The liquefaction may also contribute to the safety of coastal constructions. The assessment of liquefaction potential can be

LIQUEFACTION RESISTANCE OF GRANULATED COAL ASH
Doboku Gakkai Ronbunshuu C, 2006 造粒石炭灰のさらなる利用用途の拡大を目指し，その一つである埋立材としての利用を想定し，その際に懸念される液状化に着目した．造粒石炭灰に対して非排水繰返し三軸試験を行い，その結果を自然砂の結果と比較することにより，繰返しせん断特性を明らかにすることを目的とした．その結果，造粒石炭灰の繰返しせん断強度曲線は，拘束圧の影響を受け，曲線が緩やかになるものの，自然砂の繰返しせん断強度曲線の上方に位置することがわかった．また，造粒石炭灰は顕著な粒子破砕を示すことが認められた．そして，圧密時に起こる粒子破砕は構造の安定化に寄与するため，高い繰返しせん断強度を発揮し，せん断時の粒子破砕は，軸ひずみの発生に寄与するため，繰返しせん断強度を低下させることが推察された．
