锡林浩特市市区地震砂土液化研究
|
摘要
收集整理锡林浩特市区34个钻孔资料,采用标准贯入试验法和剪切波速法对其进行地震砂土液化的判别,结果显示:当地震烈度达到Ⅶ度时,锡林浩特市区存在砂土液化问题,并给出锡林浩特市市区砂土液化分布范围。
Standard penetration test method and shear wave velocity method are used to distinguish the liquefaction of seismic sand by collecting the data of 34 boreholes in Xilinhot city. The results show that as the seismic intensity reaches Ⅶ degree, sand liquefaction appear in the urban district of Xilinhot. Meanwhile, the distribution range of sand liquefaction in Xilinhot city is analysed in this article.
