( 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 中国地展局工程力学研究所硕士学位论文川采用《建筑抗震设计规范》 ( gb50on一2001 )基于标准贯入试验的判别法、基于场地剪切波速的液化判别方法和seed一idriss简化法对可液化场地进行了液化判别;考虑土的非线性，采用等效线性化模型，利用有限元方法进行了场地的地震反应分析;并对沪蓉高速铁路徐州段可液化场地的地震液化性能做出了综合评价。
The study on rayleigh wave characteristics in layered soil shows that shear wave velocity of soil can be attained from the raylegh wave velocity . it is well known that there is relationship between shear wave velocity and characteristics of soil . so rayleigh wave method can be used to reflect the characteristics of soil which is non - intrusive , quick , economical 许多学者对瑞利波在地基中的传播特性的研究表明，瑞利波能够反演地基土的剪切波速度，而剪切波速度跟地基土特性又有联系，因此，可以利用瑞利波法来反演地基土的特性。
