| 摘 要： | 通过对11项典型工程场地进行原位取土及双桥静力触探原位测试分析，重点研究了上海地区薄层粘性土（或粘质粉土）夹层对液化判别的影响，统计分析了锥尖阻力qc、摩阻比Rf与土层粘粒含量的相关关系，提出了完全依据双桥静力触探试验的地基液化判别方法，在工程应用中取得了显著经济效益。

| Abstract: | Based on CPT(qc, Rf ) tests in eleven representative engineerings, liquefaction estimation of sandy soils with thin clay interlayer in Shanghai area is studied. It is revealed that there are significant relationship between specific penetration resistance, friction-resistance ratio and soil clay content through statistical analysis of tested data. The liquefaction estimation method based on CPT(qc, Rf) is given. And its application shows that the method is effective. |
