This paper reports the results of dynamic centrifuge tests carried out on sandy models alternatively equipped with vertical or horizontal drains. The main aim experimentation was to investigate use drains mitigate liquefaction susceptibility deposits and validate their applicability as a remediation technique applicable in urban industrial areas protect existing buildings from liquefaction. ass...

Recent ground failure case histories after 1994 Northridge, 1999 Kocaeli and 1999 Chi-Chi earthquakes revealed that low-plasticity silt-clay mixtures generate significant cyclic pore pressures and can exhibit a strain-softening response, which may cause significant damage to overlying structural systems. In this study, results of cyclic tests performed on undisturbed specimens of ML, CL, MH and...

Abstract Mapping the susceptibility of earthquake-induced soil liquefaction at continental scale is a challenge. Susceptibility soils to tendency certain geomaterials undergo severe stiffness degradation and loss shear strength. The latter could be induced by cyclic loading seismic events. surface evidence local phenomenon, detailed geotechnical field investigations are not available for region...

The main purpose of this study is to develop a Geospatial Information System (GIS) model with the ability to assess the seismic damage to pipelines for two well-known hazards, including ground shaking and ground failure simultaneously. The model that is developed and used in this study includes four main parts of database implementation, seismic hazard analysis, vulnerability assessment and sei...

Abstract Understanding and quantifying the hazards related to earthquake-induced submarine liquefaction landslides are particularly significant offshore of tropical volcanic-carbonate islands, where carbonate production competes with volcanism create highly contrasted lithological successions. To improve detection liquefaction-prone layers, we analyzed physical properties mineralogy performed 7...

Creosoteand chromated copper arsenate (CCA)-treated wood waste and untreated southern pine wood were liquefied with phenol and sulfuric acid. The effects of sulfuric acid content, liquefaction time, liquefaction temperature, and phenol to wood ratio on liquefaction rate (i.e., wood residue content) were investigated and analyzed by analysis of variance (ANOVA). The results showed that both creo...

. The earthquakes of 1894, 1944, 1952 and 1977 occurred in the province San Juan central-wesern Argentina caused numerous processes soils sediment liquefaction, including those Ullum-Zonda valley. Historical records showed cracks, sand volcanoes, craters differential settlements, which significant damage to housing agro-industrial sector region. In this work, we carried out a study susceptibili...
