ISO 14688-1:2017规定了土壤识别和描述的规则，并打算与ISO 14688？2一起阅读，其中概述了工程用土壤最常用的材料特性的分类基础。相关特征可能会有所不同，因此，对于特定项目或材料，可以对描述性和分类术语进行更详细的细分。 ISO 14688-1:2017规定了基于灵活系统的土壤识别和描述程序，供有经验的人员使用，通过视觉和手动技术涵盖材料和质量特征。 详细说明了用于识别土壤的各个特征和经常使用的描述性术语，包括与作为描述过程一部分在现场进行的手工测试结果相关的术语。 ISO 14688-1:2017适用于工程用土壤的描述，这些土壤可以是通过自然过程铺设的土壤，也可以是由人工铺设的土壤或包含合成材料的土壤。 注1:ISO 14689-1涵盖了岩石的识别和描述。使用本文件中的程序、ISO 14688-2和ISO 14689对土壤和岩石之间的中间材料进行识别和描述- 1视情况而定。 注2:ISO 25177涵盖了土壤学用途的土壤识别和分类，以及土壤保护和污染区域修复测量框架内的土壤识别和分类。

ISO 14688-1:2017 specifies the rules for the identification and description of soils and is intended to be read in conjunction with ISO 14688？2, which outlines the basis of classification of those material characteristics most commonly used for soils for engineering purposes. The relevant characteristics could vary and therefore, for particular projects or materials, more detailed subdivisions of the descriptive and classification terms could be appropriate. ISO 14688-1:2017 specifies procedures for the identification and description of soils based on a flexible system for use by experienced persons, covering both material and mass characteristics by visual and manual techniques. Details are given of the individual characteristics for identifying soils and the descriptive terms in regular use, including those related to the results of hand tests carried out in the field as part of the descriptive process. ISO 14688-1:2017 is applicable to the description of soils for engineering purposes which can be those laid by natural processes, those laid by man or comprise synthetic materials. NOTE 1 The identification and description of rocks are covered by ISO 14689-1. Identification and description of materials intermediate between soil and rocks are carried out using the procedures in this document, ISO 14688？2 and ISO 14689-1 as appropriate. NOTE 2 The identification and classification of soil for pedological purposes, as well as in the framework of measurements for soil protection and for remediation of contaminated areas, is covered by ISO 25177.
