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).

Calculating the state parameter in crushable sands [PDF]
, 2019 The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

Effect of Static Shear on Resistance to Liquefaction [PDF]
Soils and Foundations, 1983 ABSTRACT The influence of static shear on undrained cyclic loading behaviour of Ottawa sand has been studied using triaxial samples anisotropically consolidated to various stress ratios. It is shown that the presence of static shear does not always lead to increased resistance to liquefaction or cyclic strain development.

Correlations between the stress paths of a monotonic test and a cyclic test under the same initial conditions [PDF]
, 2017 In most experimental studies on liquefaction, cyclic loadings are applied on specimens with various initial conditions. However, few studies compared cyclic test results with monotonic results under the same initial conditions.

The importance of accurate time-integration in the numerical modelling of P-wave propagation [PDF]
, 2017 The numerical dissipation characteristics of the Newmark and generalised-α time-integration schemes are investigated for P-wave propagation in a fully saturated level-ground sand deposit, where higher frequencies than those for S-waves are of concern ...

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.
