- 摘要:
- 饱和砂土地震液化是一种国内外普遍存在的不良地质作用。许多国外建设项目要求采用欧盟或美国规范标准进行地震液化判别,与中国现行规范标准推荐的方法有明显区别。利用现场静力触探试验的结果,采用美国国家地震工程研究中心(National Center for Earthquake Engineering Research,NCEER)判别法(以下简称NCEER法)、美国加州大学教授Boulanger R W和Idriss I M判别法(以下简称Boulanger-Idriss 2014法)和中国铁路规范判别法(以下简称铁路规范法),对国内外251个已发生的地震实例进行砂土地震液化验算和讨论。结果显示,3种判别方法的多数结果符合实际情况。建议海外工程项目采用Boulanger-Idriss 2014法和NCEER法;中国项目采用中国铁路规范法时,建议用颗粒分析和液塑限试验结果取代摩阻比以划分土体类型。研究成果对静力触探判别地震液化有参考价值。
Earthquakeinduced liquefaction of saturated sandy soils is a common geological hazard worldwide. Many overseas project owners require the application of US or EU standards and codes, which differ significantly from the liquefaction assessment methods recommended in current Chinese standards. Based on cone penetration test(CPT) results, the National Center for Earthquake Engineering Research(NCEER) method, the Boulanger R W and Idriss I M criterion proposed by these two professors at the University of California, USA (hereinafter referred to as the Boulanger-Idriss 2014 method), and the Chinese Railway Code method were applied to re-evaluate and discuss 251 documented earthquake-induced liquefaction cases from around the world. The results indicate that all three methods are reliable in most cases. The Boulanger-Idriss 2014 method and the NCEER method are recommended for overseas construction projects. When applying the Chinese Railway Code method, it is recommended that grain size distribution analysis and Atterberg limit tests be used in place of friction ratio to classify soil types. The findings provide a useful reference for CPT-based earthquake-induced liquefaction assessment.
