Analysis on the effect of three earthquake-induced liquefaction triggering procedures using Standard Penetration Test
Liquefaction of saturated soils on-site is a widespread adverse geological phenomenon encountered in engineering projects.Most overseas project owners mandate adherence to the US or EU standards for assessing soil liquefaction risks.Notably,there are significant differences between the Chinese codes and the US or EU standards in this aspect.Based on the results of Standard Penetration Test(SPT),this study applies three liquefaction triggering procedures-the NCEER Method,Boulanger-Idriss 2014 Method and the method recommended by the Chinese Code for Seismic Design of Buildings to analyse and discuss 230 earthquake cases worldwide.The results show that these methods generally provide reliable assessments that are consistent with reality.Boulanger-Idriss 2014 Method aligns most closely with the actual conditions,whereas the Chinese seismic method is noted for its simplicity,easy of use,and conservative nature.For overseas projects,Boulanger-Idriss 2014 Method and NCEER Method are recommended,while the Chinese seismic code method is deemed suitable for domestic projects.The results provide valuable reference for earthquake-induced liquefaction assessment using Standard Penetration Test.
