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 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.

La boîte à outils géotechnique de demain: conception des structures géotechniques selon EN 1997: 202x [PDF]
, 2019 This paper shows how three new concepts – ‘Design Cases’ (introduced in prEN 1990), the ‘Geotechnical Design Model’ (prEN 1997-1), and the ‘Ground Model’ (prEN 1997-2) – are combined (in prEN 1997-3) to provide a comprehensive and flexible set of tools ...

Resistance of Soil to Liquefaction and Settlement
Soils and Foundations, 1971 This paper presents a quantitative method of organizing field observations concerning liquefaction and non-liquefaction during actual earthquakes. The ratio τc/σ^-V is evaluated for 13 sites affected by 8 earthquakes and plotted against relative density (τc is the average peak dynamic stress during the earthquake, and σ^-V is the vertical effective ...

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．

Nondestructive Testing of Welded Composite Metal Foams
Advanced Engineering Materials, EarlyView.X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.
