Evaluation of liquefaction potential by standard penetration test and shear wave velocity methods: a case study

Abstract

Dynamic loads, such as earthquakes, can cause damage to soils, especially from soil liquefaction.Liquefaction analyses provide more reliable results when combined with the properties of soils and earthquakes. In recent years, computer programs have been developed in which many parameters can be used to perform these analyses for solving geotechnical engineering problems. SoilEngineering is a Microsoft Excel-based geotechnical design program with which calculations can be carried out and graphical results can be achieved based on empirical relationships. In this study, the effects of soil and earthquake parameters on soil liquefaction were analyzed using a standard penetration test (SPT) and shear wave velocity (Vs). We observed that there is conformity between the parameters used in different techniques. Taken together, our results show that calculating the liquefaction risk using both soil and earthquake properties will produce reliable results in solving geotechnical problems.

Evaluation of Shear Wave Velocity Prediction Models from Standard Penetration Test N Values Depending on Geologic Attributes: A Case Study in Busan, South Korea

“…These findings emphasize the importance of considering the geological context and terrain characteristics when assessing and refining N-V S relationships for predicting V S in different regions. The validated N-V S models presented in this study, tailored to specific geological conditions, can prove valuable in scenarios requiring accurate V S estimations, such as liquefaction assessments using V S values [35][36][37][38][39][40][41][42].…”

“…Afterward, the topic caught our attention, and many soil liquefaction studies DOI: 10.4236/ijg.2023.1411055 1086 International Journal of Geosciences have been conducted and reported in the past decades. Such studies include soil liquefaction assessment methods [2]- [9], liquefaction potential case studies [10]- [15], and soil liquefaction occurrence mechanisms [16] [17] [18], among others [19]- [27].…”
