简要介绍国际上常用的英美规范关于土的粒组划分、土的筛分网眼规格、岩石的岩质划分、岩石层厚划分、岩石风化等级划分标准等内容,并与国内规程规范的有关标准进行对比分析,概括总结了英美规范与国内规范对于岩石和土的几个重要的工程性状描述方面的差异,进而评价各自工程适应性;在此基础上,论述了这种差异可能对岩土评价的造成影响。希望对今后我国工程技术规范发展有一定的借鉴意义,也能够使得技术人员清楚认识这种差异及其可能的影响,从而灵活运用。
This paper briefly introduces the commonly used Anglo-American norms on soil classification, classification of soil mesh size, rock lithology classification, rock layer thickness classification, rock weathering grade classification standards and other relevant standards of the national code of conduct Through the comparative analysis, this paper summarizes the differences between the British and American norms and the domestic norms in describing some important engineering traits of rock and soil, and then evaluates the adaptability of each project. On this basis, it discusses that this difference may affect the geotechnical evaluation Affect. I hope that in the future development of our country’s engineering and technical specifications have some reference, but also can make the technical staff clearly aware of this difference and its possible impact, and thus flexible use.
