砂土液化判别国内外规范对比研究

Comparative Study on Liquefaction Discrimination Methods at Home and Abroad

砂土液化是地基失稳主要因素之一,液化判别是减轻震害的有效手段。国外主流液化判别方法与国内标准存在较大差异,该文从判别方法理论基础角度出发阐述异同点。并列举一应用实例,对比分析判别结论差异性。

Liquefaction is one of the main causes of foundation instability, and liquefaction discrimination is an effective means to ease earthquake damage. The mainstream approach of liquefaction discrimination is quite different from that of other countries. From the perspective of the theoretical basis of discrimination methods, the similarities and differences of these methods are demonstrated, with one case presented to verify the results.
