Calibration of Finn Model and UBCSAND Model for Simplified Liquefaction Analysis Procedures
Applied Sciences, 2021 Soil-liquefaction-related hazards can damage structures or lead to an extensive loss of life and property. Therefore, the stability and safety of structures against soil liquefaction are essential for evaluation in earthquake design.

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．

On the prediction of liquefaction resistance of unsaturated sands
Soil Dynamics and Earthquake Engineering, 2019 Abstract The increasing interest in the undrained cyclic behaviour of unsaturated soils is justified by the evidence of the beneficial effect of desaturation on liquefaction resistance and is thus strictly connected with the need to put forth sound tools to be used in the design of Induced Partial Saturation (IPS) interventions. IPS is still far from
