Bangladesh is one of the world's most disaster-prone areas. The northwest region seismically active region. Dinajpur district closest to Himalayan frontal thrust, making it vulnerable earthquake-related liquefaction. Therefore, in-situ parameters are used assess liquefaction susceptibility subsurface geology for in terms soil safety factor (FS), potential index (LPI), and probability (PL). This...

in this study, a low-cost, rapid and qualitative evaluation procedure is presented using dynamic pattern recognition analysis to assess liquefaction potential which is useful in the planning, zoning, general hazard assessment, and delineation of areas, dynamic pattern recognition using neural networks is generally considered to be an effective tool for assessing of hazard potential on the basis...

Abstract Central Sulawesi Province is one of the areas in Indonesia that prone to large earthquakes. Balaroa, Petobo, and Sibalaya were among most fatalities damaged facilities infrastructure due earthquake on September 28th 2018. Around Balaroa Village, besides huge damages Perumnas Housing, area around housing was also affected, for example Jamur, Kelor, Labu streets, many houses buildings da...

Abstract The activity of the Opak Fault on May 27 th , 2006, caused a strong earthquake M w 6.3, then known as Yogyakarta Earthquake. Previous studies have shown that several damages during were by liquefaction. This paper aims to determine potential liquefaction hazards at toll road construction in Klaten Regency, within less than 10 km Fault. was analyzed from Standard Penetration data using ...

Comparing to the conventional bath heating, the effects of liquefaction parameters on the degree of liquefaction of wood in polyhydric alcohols by using microwave as an energy source were evaluated. Polyurethane foams were successfully prepared from the liquefied biomass-based polyols. The effects of heating methods (conventional bath heating and microwave) and liquefaction reaction time on the...

This study refers to the prediction of liquefaction potential of alluvial soil by artificial neural network models. To meet the objective 160 data sets from field and laboratory tests were collected for the development of ANN models. Initially these data sets were used to determine liquefaction parameters like cyclic resistance ratio and cyclic stress ratio by Idriss and Boulanger method to ide...

Zhao (eds.), Bifurcation and Degradation of Geomaterials in the New Millennium, Springer Series in Geomechanics and Geoengineering, DOI 10.1007/978-3-319-13506-9_38 Abstract Micromechanical change in packing structures can provide significant insights to better understand the cyclic mobility and post-liquefaction behaviors o...

Paul C. Rizzo Associates, Inc. (RIZZO) has developed efficient computational tools to evaluate the liquefaction potential of earth embankment dams located within high risk seismic regions. Two relevant case histories are the Saluda Dam and the Santee Cooper East Dam Extension, both structures susceptible to liquefaction, and located in South Carolina. Saluda Dam presents liquefaction risks with...

This study describes a general liquefaction flow instability criterion for elastoplastic soils based on the concept of loss of uniqueness. We apply the criterion to the general case of axisymmetric loading and invoke the concepts of effective stresses and loss of controllability to arrive at a general criterion for the onset of liquefaction flow. The criterion is used in conjunction with an ela...

one of the important problems in earthquake geotechnical engineering is liquefaction phenomenon that happens in loose saturated granular soils. in this study, 11 boreholes from govanjik and dayalar area in downstream of sattarkhan dam collected and evaluated. results of research are showed that with assuming cementation in soils, liquefaction potential is weak to moderate than non-cemented cond...
