ISO 14689:2017规定了根据矿物成分、成因、结构、粒度、不连续性和其他参数识别和描述岩石材料和岩体的规则。它还提供了描述其他特征及其命名的规则。 ISO 14689:2017适用于土木工程中岩土工程和工程地质的岩石描述。该描述是在岩芯和其他岩石样品以及岩体暴露上进行的。 使用一个或多个描述性参数来建议可能的岩体行为的岩体分类系统超出了本文件的范围（见参考文献）。 注:ISO 14688-1和ISO 14688-2涵盖了工程用土壤的识别和分类。在适当情况下，使用ISO 14688-1、ISO 14688-2和本文件中的程序识别和描述土壤和岩石之间的中间材料。

ISO 14689:2017 specifies the rules for the identification and description of rock material and mass on the basis of mineralogical composition, genetic aspects, structure, grain size, discontinuities and other parameters. It also provides rules for the description of other characteristics as well as for their designation. ISO 14689:2017 applies to the description of rock for geotechnics and engineering geology in civil engineering. The description is carried out on cores and other samples of rock and on exposures of rock masses. Rock mass classification systems using one or more descriptive parameters to suggest likely rock mass behaviour are beyond the scope of this document (see Bibliography). NOTE Identification and classification of soil for engineering purposes are covered in ISO 14688？1 and ISO 14688？2. Identification and description of materials intermediate between soil and rock are carried out using the procedures in ISO 14688？1, ISO 14688？2 and this document, as appropriate.
