Liquefaction Resistance From a Ductility Viewpoint
Soils and Foundations, 2000 Very few attempts have been made to evaluate the liquefaction resistance from a ductility viewpoint. The authors propose a new method to evaluate the ductility of soils against liquefaction, based on the energy dissipation capacity obtained from stress-strain loops of the constant-strain-controlled cyclic triaxial test.

Liquefaction Resistance of A Partially Saturated Sand
Soils and Foundations, 1989 ABSTRACT Cyclic torsional shear tests on hollow cylindrical specimens were conducted to investigate the effects of degree of saturation on the undrained cyclic shear strength (liquefaction resistance) of air-pluviated Toyoura sand at a relative density of 60 percent. The tests showed that (1) the liquefaction resistance increased significantly with a

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.

Liquefaction evaluation of dam foundation soils considering overlying structure
Journal of Rock Mechanics and Geotechnical Engineering, 2015 The liquefaction analysis procedure conducted at a dam foundation associated with a layer of liquefiable sand is presented. In this case, the effects of the overlying dam and an embedded diaphragm wall on liquefaction potential of foundation soils are ...

Effect of membrane penetration on liquefaction resistance
Effect of membrane penetration on liquefaction resistanceThe liquefaction of saturated sand is due to a negative dilatancy. In the cyclic triaxial test, a part of pore water squeezed from sample is transformed into the reduction of membrane penetration and so the perfect undrained test can not be performed. Consequently, the liquefaction resistance obtained by the cyclic triaxial test is evaluated apparently

Geotechnics, 2022 Earthquake-induced liquefaction is one of the major causes of building damage as it decreases the strength and stiffness of soil. The liquefaction resistance of soils increases significantly as the degree of saturation decreases, making soil desaturation
