砂土地基液化与液化后结果的研究

Review on liquefaction and post-liquefaction behavior of sand

通过对近 3 0年来国内外有关砂土液化方面主要科研成果的回顾 ,对自由场地砂土液化产生的原因、影响因素、主要判别方法和对已有建筑物地基液化研究 ,以及对液化后结果现状的综述 ,得出液化研究目前还停留在以野外调查为主、室内理论性研究及有限元、三维模型的研究还较少 ,有待于我们及早进行研究解决。

Some major results both inland and abroad of the study on analysis methods of liquefaction and post liquefaction of sand in the past 30 years are reviewed in this paper. The reason of the free site, the affect factors and some distinguishing methods on liquefaction of sand are studied. Besides the present state of the study on the liquefaction of the existed building foundation is described. Some conclusions are arrived. Paper points out that at present the research on the liquefaction is dominantly more focused on the field investigation rather than the theoretical study in laboratory, the researches of limited element and 3D, which need being studied more in the future.
