饱和土液化判别公式的讨论
|
摘要
对2010版和2001版建筑抗震设计规范中饱和土液化判别公式进行了分析和讨论,指出了液化初判公式中几个尚未考虑到的问题;重点讨论了两本规范在液化判别公式形式、判别深度以及参数取值等方面的不同点,并得出了一些有益的结论,具有一定指导意义。
The paper undertakes the analysis and discussion on the identification formula for liquefaction of saturated soil in the Architectural Anti-seismic Design Regulations in 2010 and 2001,points out some unconsidered problems in the initial liquefaction identification formula,mainly discusses the differences of the two liquefaction identification formula in the identification forms of the liquefaction,the identification depth,and the parameter value,and achieves some beneficial conclusions,so as to have the direction significance.
