( 4 ) to determine liquefaction potential in site, several viable approaches are used, and these are ( 1 ) the standard penetration test ( spt ), ( 2 ) measurement of in - situ shear wave velocity ( vs ), and ( 3 ) use of test data and seed & idriss method. considering the non - linear of the soil, we calculate the earthquake response of the soil with the hardin - drnevich model and the finite element method. finally, we estimate the liquefaction capability of the site during earthquake in xuzhou, jiangsu province
中國地展局工程力學研究所碩士學位論文川採用《建築抗震設計規范》 （ gb50on一2001 ）基於標準貫入試驗的判別法、基於場地剪切波速的液化判別方法和seed一idriss簡化法對可液化場地進行了液化判別;考慮土的非線性，採用等效線性化模型，利用有限元方法進行了場地的地震反應分析;並對滬蓉高速鐵路徐州段可液化場地的地震液化性能做出了綜合評價。
