中文摘要: |
面波速度与剪切波速度、标准贯入锤击数之间存在一定的换算关系,通过面波频散曲线的拟合结果,可以计算出地下不同速度层的剪切波速度和标准贯入锤击数。文章以面波速度为基础,分别运用两种方法评价液化地基的处理效果,并与标准贯入试验的结果进行对比,分析两种方法的准确性和差异性。对比结果表明:通过面波速度计算标准贯入锤击数对处理效果的评价与标贯试验的实测结果更加吻合。 |
英文摘要: |
There is certain relationship among the surface wave velocity, the secondary wave velocity, and standard penetration blow number and the latter two parameters of underground different velocity layers can be obtained with fitting result of the surface wave frequency scattering curve. In this paper, authors, on the basis of surface wave velocity, used respectively two methods to evaluate liquefaction the processing result of the foundation liquefaction, and compared them with the result of the standard penetration test, so as to analyze the accuracy and the difference of two methods, which shows that the evaluation on the process result from the standard penetration blow number calculated from the surface wave velocity is more consistent with actual measurement result from the standard penetration test than. |
