国内外规范关于岩土性状描述的对比研究

Contrasting Study on Property Description of Rocks and Soils between Chinese Specifications and Foreign Standards

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。

The international classification standards of rocks and soils for the gain, the size of sieving net of soil, the hardness, the thickness and the weathering of rock are briefly introduced and the contrasting analysis on the Chinese standards and foreign standards are carried out. The differences of the description of engineering behavior for rocks and soils between the Chinese specifications and the British and American standards are summarized, and their applications in engineering practice are evaluated. The influences of the differences on the assessment of rocks and soils are discussed.
