The main objective of this study is to identify the most suitable method for liquefaction analysis based on factor of safety and Performance Fitness Error Metrics (PFEMs), Rank analysis, Gini index, etc. The contribution of various independent variables, such as corrected SPT N values, fine ...
A technique that was used to estimate the safety factor against liquefaction by predicting the increase in SPT N-values due to driving of displacement piles in sand is presented. The prediction method involved applying previously-developed relations between relative density, grain-size distribution, ove...
In the new survey data of soil liquefaction evaluation model established of five parameters by the earthquake intensity, the measured SPT counts, datum SPT values, groundwater level, and sand buried depth. The datum SPT values, the influencing coefficients of water and sand depths are gain by a...
performance indices, including rank analysis, accuracy matrix, and AIC criteria. The comparative analysis of the proposed models' predictive ability to determine liquefaction probability revealed that the RNN model outperformed the others, displaying the highest accuracy and lowest error index values. Subse...

Note that liquefaction assessment requires the SPT N-value to be corrected for overburden pressure in addition to the standard corrections. N60 values corrected by a correction factor for overburden is denoted as N1(60). ( 1) 60 = . 60 (2) = min [1.5, √9 8′ ] (3) Equation 3 is...
Standard Penetration Test N values become very important in earthquake geotechnical engineering because of a good correlation with an index of soil liquefaction and also provides the basis for site response and microzonation studies. Many researchers have published Converted and modified correlations Most...
Standard Penetration Test (SPT) results have been evaluated for potential liquefaction assessment. The soils are mainly composed of very loose to loose sands... ATMS Hossain,MS Mahabub,T Dutta,... - 地震研究(英文) 被引量: 0发表: 2023年 Assessing Susceptibility to Soil Liquefaction Using the ...
shallow depth i.e. ≤6 m, Kirar and Maheshwari [14] examined the dynamic soil properties at high strain using cyclic triaxial tests for four sites [2–5] listed in Table1, Muley et al. [15] evaluated liquefaction potential of first five sites listed in Table1. Index properties and SPT...
