关键土力学指标在国内外规范间的对比分析

The comparative analysis of key soil mechanical parameters between national and foreign standards

若干关键土力学指标,如液限、塑限及土粒组划分、土命名、标准贯入试验等的试验方法与划分标准在国标、英标及美标的岩土工程相关规范间差异较大,本文通过规范间相应指标的对比分析,结合相关工程经验,初步探讨指标使用过程中的相互转化或经验关系,有利于关键土力学指标在不同规范间之间融合,为同类工程提供参考。

The experimental methods and division standard for several key soil mechanical parameters,such as liquid limit,plastic limit,and soil particles division,name determination and standard penetration test etc. are quite different among Chinese,British and American standards. After comparative analysis among different standards about these parameters,considering related engineering experience,the mutual transformation and experience relationship between these parameters in different standards are discussed preliminarily,so as to facilitate the using of these key soil parameters and to provide reference for the similar project.
