Construction of CPT-based Liquefaction Database from 2003 Bachu Earthquake

  • 摘要: 2003年2月24日新疆巴楚—伽师地区发生MS6.8地震,出现了唐山地震、海城地震后近30年我国大陆最具规模的砂土液化现象。大量研究显示,巴楚地震液化砂土标贯击数与锥尖阻力指标偏大,采用国内外液化判别方法往往会判为非液化。利用Robertson土质分类图对巴楚地区孔压静力触探试验(CPTU)数据进行土类分层检验,基于以下原则,选定了液化点液化层与非液化点临界液化层。(1)应选取非液化点土层剖面中最易液化层,不能因液化点力学指标偏大而将非液化点临界液化层力学指标选得更大;(2)应结合qc-hRf-h图,避免选取黏土为液化层;(3)巴楚地区液化层往往上覆非饱和细砂,形成透水边界,选取液化层时应舍弃存在透水边界的土层。最后,利用我国规范方法构建了巴楚地震静力触探(CPT)液化数据库,并进行了初步的判别分析。
