BS EN ISO 14688-2:2018规定了这些材料特性分类的基本原则 最常用于工程用土壤。本书旨在结合阅读 符合ISO 14688-1，其中给出了土壤识别和描述的规则。相关的 特征可能会有所不同，因此，对于特定的项目或材料，需要进行更详细的细分 描述和分类术语的定义可能是合适的。由于当地地质条件的差异 使用条件和实践来提高相关分类标准。本文件中确立的分类原则允许将土壤分为以下几类: 相似的成分和岩土性质，基于现场和实验室试验的结果 考虑其适用于岩土工程目的。本文件适用于现场天然土壤、人工改造的天然土壤和合成土壤 材料。EN 16907-2中给出了具体用于土方工程的更详细分类。交叉引用:ISO/TS 17892-12ISO 17892-2ISO/TS 17892-11ISO/TS 17892-9ISO 17892-1ISO/TS 17892-10ISO 17892-6ISO 17892-5ISO 14689ISO/TS 17892-7ISO 17892-3ISO/TS 17892-8ISO 17892-4ISO 14688-1:2017ISO 22476-1ISO 22476-2ISO 22476-8ISO 22476-4ISO 22476-3ISO 22476-6EN 16907ISO 25177EN 1997-2:2007EN 16907-2购买本产品时可提供的所有现行修订版文件

BS EN ISO 14688-2:2018 specifies the basic principles for classification of those material characteristics most commonly used for soils for engineering purposes. It is intended to be read in conjunction with ISO 14688-1, which gives rules for the identification and description of soils. The relevant characteristics could vary and therefore, for particular projects or materials, more detailed subdivisions of the descriptive and classification terms could be appropriate. Due to differences in local geological conditions, practices to enhance relevant classification criteria are used.The classification principles established in this document allow soils to be classified into groups of similar composition and geotechnical properties, based on the results of field and laboratory tests with respect to their suitability for geotechnical engineering purposes.This document is applicable to natural soil in situ, natural soil reworked artificially and synthetic materials. A more detailed classification specific to use in earthworks is given in EN 16907-2.Cross References:ISO/TS 17892-12ISO 17892-2ISO/TS 17892-11ISO/TS 17892-9ISO 17892-1ISO/TS 17892-10ISO 17892-6ISO 17892-5ISO 14689ISO/TS 17892-7ISO 17892-3ISO/TS 17892-8ISO 17892-4ISO 14688-1:2017ISO 22476-1ISO 22476-2ISO 22476-8ISO 22476-4ISO 22476-3ISO 22476-6EN 16907ISO 25177EN 1997-2:2007EN 16907-2All current amendments available at time of purchase are included with the purchase of this document.
