天津某地区第Ⅰ海相沉积层顶部饱和粉土层液化分析

Liquefaction Analysis of Saturated Mealy Soil Layer on Top of Part Ⅰ Marine Deposit Layer in Tianjin

概要:根据几十项工程的工程勘察资料,按现行规范中提供的标准贯入判别法和静力触探判别法两种判别液化的方法分别进行了计算分析,得出了计算分析结果与宏观调查之间存在较大的差异,同时对产生差异的原因进行了分析,并提出了初步的解决方案,可供在天津地区从事岩土工程勘察、设计等人员的借鉴及参考。

The survey data on dozens of projects have been calculated and analyzed via two liquefaction discrimination methods in the existing norms, i.e. standard penetration discrimination and static cone penetration discrimination, which shows a striking dissimilarity between the calculated value and the macro survey result. Meanwhile, the causes for the above difference have been analyzed in order to obtain a preliminary solution which serves as a reference for the surveyors and designers in charge of Tianjin area geotechnical work.
