基于土壤分类的ASTM（美标）与国标之异同研究

在建设工程中，规范和标准是勘察设计人员工作的依据。使用规范的准确与否，关系到最终成果的可靠性和质 量保证。越来越多的境外工程要求使用当地标准或美标、欧标，但是国内几乎没有专业人员从事土工试验美标或欧标的研 究，本文就美国ASTM标准和国标中关于土的分类部分进行分析比较，以便更好地为境外工程服务。

On similarities and differences between national standard and ASTM based on soil classification

In the construction project, norms and standards are the basis for the engineering survey and design of works. The utilization of specifications relates to the reliability and quality of the final result. At present, a growing number of overseas projects require to use the local standard or the American standard and European standard, but almost no domestic professionals are engaged in the American standard or European standard on the soil test. This paper focuses on the comparison of the U.S. ASTM standards and the national standards on the soil classified section, so as to serve for the overseas engineering.
