The potential for liquefaction triggering of a soil under a given seismic loading is measured herein by probability of liquefaction. The first order reliability method FORM is used to calculate reliability index, from which the probability of liquefaction is obtained. This approach requires the knowledge of parameter and model uncertainties; the latter is the focus of this paper. An empirical m...

The liquefaction vulnerability of soil is generally related to a few parameters which are ordinarily measured by laboratory tests on distributed and undistributed under distinctive test conditions. This study uses methods based standard penetration assess criteria appraise the for deposits Chalus City placed in high seismic area. To overcome deficiencies these experimental strategies an ANN-bas...

The use of the shear wave velocity data as a field index for evaluating the liquefaction potential of sands is receiving increased attention because both shear wave velocity and liquefaction resistance are similarly influenced by many of the same factors such as void ratio, state of stress, stress history and geologic age. In this paper, the potential of support vector machines (SVM) based clas...

Severe soil liquefaction due to a long duration earthquake with low acceleration occurred at Tokyo Bay area in the 2011 off the Pacific coast of Tohoku Earthquake. This phenomenon clearly shows that soil liquefaction is affected by properties of input waves. This paper describes effect of wave properties of earthquake on liquefaction using effective stress analysis with some earthquakes. Analyt...

Simplified techniques based on in situ testing methods are commonly used to assess seismic liquefaction potential. Many of these simplified methods are based on finding the liquefaction boundary. As the liquefaction classification problem is highly nonlinear in nature, it is difficult to develop a comprehensive model taking into account all the independent variables, such as the seismic and soi...

Purpose: To explore changes in the characteristics of water-in-oil-based high internal phase emulsion containing Moringa oleifera (Moringa HIPE) extract at various storage conditions and time intervals. Methods: Moringa leaves extract (3 %) was entrapped into HIPE. Color, liquefaction, conductivity, pH, and centrifugation were assessed by keeping the samples of Moringa HIPE at 8, 25, 40 and 40 ...

Soil liquefaction is the phenomenon of temporary loss of shear of saturated cohesionless soil under the influence of vibrations caused by earthquakes. The extensive loss of lives and civil infrastructure system like buildings, bridges, highways etc. caused by liquefaction emphasize the need for strong and reliable methods for evaluating the liquefaction potential of sites. Simplified techniques...

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 b...
