| 摘 要： | 土的工程分类是岩土工程设计中的一项基础性工作。结合某实际工程土石坝基砂层勘测资料,依据《岩土工程勘察规范》(GB50021-2001)和《土的工程分类标准》(GB/T50145-2007)两种常用的分类方法,对341个实际砂土样进行定名;按照定名结果,对覆盖层砂土样级配包络线、物理力学性质参数进行统计分析;并据此对两种分类方法的特点进行对比分析。

| Abstract: | The classification of soil is an elementary part of geotechnical engineering design.This classification allows for a preliminary qualitative judgment of the characteristics of a soil.Furthermore, using a set of criteria,the soil can be classified that can assist in how it can be employed in an engineering project.In this paper,sand layer survey data of an embankment dam foundation, were subjected to two common classification methods,the code for investigation of geotechnical engineering (GB50021-2001) and standard for engineering classification of soil(GB/T50145-2007).Three hundred and forty-one sand samples were classified using these two methods.The results of this classification allowed for a statistical analysis of grading envelope,and the physical and mechanical properties of the covering layer sand samples.Finally,the characteristics of the two classification methods were compared according to the results of the statistical analysis. |
