中国、美国、孟加拉国三国现行抗震设计规范中针对细粒土的液化判别标准各不相同.为提出可供工程应用及中国规范修订参考的评判标准,该文通过对比三国判别流程和标准,并分析其形成过程后,在孟加拉国达卡及周边城市采取的168个细粒土样液化判别应用基础上,综合评价了各判别流程和标准的合理性.最后提出了一套融合各标准的细粒土液化判别流程及其结果评价标准.
Comparison of Chinese,American,and Bangladeshi Criteria for Liquefaction Judgment of Fine-Grained Soil
The criteria for liquefaction judgment of fine-grained soil in current seismic design codes of China,the United States,and Bangladesh are quite different.In order to propose the judgment criteria for engineering application and Chinese code revision,this paper compared the judgment processes and criteria of the three countries.After analyzing the formation process,based on the application of the criteria for liquefaction judgment of 168 fine-grained soil samples collected in Dhaka,Bangladesh and surrounding cities,the rationality of each judgment process and criteria was evaluated comprehensively.Finally,a set of judgment processes and result criteria for fine-grained soil liquefaction integrating all criteria were put forward.
