砂土液化判别的研究现状及存在问题
|
摘要
就目前国内外砂土液化机理研究、砂土液化动力分析方法及液化判别方法等方面的研究现状做了简要归纳和评述.在液化判别方法方面,主要认为目前有Seed简化分析法、经验分析法、概率统计分析法、室内试验分析法及土层反应分析法等方法.最后,对砂土液化判别研究方面的一些不足之处提出了解决的思路.
Great achievements have been attained in the research of liquefaction distinguishing method of sands recently.In this paper the recent advances in liquefaction mechanism research,liquefaction dynamic analysis and liquefaction dis-tinguishing method of sands are reviewed.Liquefaction distinguishing method of sands can be divided as Seed simplification analyzing method,empirical analyzing method,probability statistic analyzing method,indoor experiment and numerical method.Etc.At last a few deficiencies are pointed out in researches of liquefaction distinguishing.To overcome these deficiencies,further studies are suggested.
