本文件涉及土壤、岩石和地下水取样原则，作为岩土工程勘察和测试计划的一部分。 注1:根据EN？1997-1和EN？1997-2，本文件满足土壤、岩石和地下水取样要求，以及作为岩土工程勘察和测试计划一部分的地下水测量要求。 此类地面调查的目的是: a） 恢复土壤、岩石和水样，其质量适合于评估场地对岩土工程的总体适用性，并在实验室中确定所需的地面特征； b） 获取有关地层和不连续面的层序、厚度和方向的信息； c） 确定地层的类型、组成和条件； d） 获取有关地下水条件的信息，并恢复水样，以评估地下水、土壤、岩石和建筑材料的相互作用。 不包括用于农业和环境土壤调查的土壤取样。 注？2？ISO？18400系列中提供了用于这些目的的土壤采样指南，包括污染或潜在污染场地的采样指南。ISO？18400-204还提供了土壤（地面）气体取样和测量指南。 注3:本文件中介绍的取样方法可能不适用于所有类型的土壤，例如具有强纤维结构的泥炭。 注4:本文件中的一些取样方法适用于土壤和岩石。 不包括为质量控制、质量表征和水污染源（包括底部沉积物和淤泥）识别而进行的水取样。 注？5？用于这些目的的水取样可在ISO 5667系列中找到。

This document deals with principles of sampling of soil, rock and groundwater as part of the programme of geotechnical investigation and testing. NOTE？1？This document fulfils the requirements for sampling of soil, rock and groundwater, and groundwater measurements as part of the programme of geotechnical investigation and testing according to EN？1997-1 and EN？1997-2. The aims of such ground investigations are: a) to recover soil, rock and water samples of a quality appropriate to assess the general suitability of a site for geotechnical engineering purposes and to determine the required ground characteristics in the laboratory; b) to obtain information on the sequence, thickness and orientation of strata and discontinuities; c) to establish the type, composition and condition of strata; d) to obtain information on groundwater conditions and recover water samples for assessment of the interaction of groundwater, soil, rock and construction material. Soil sampling for the purposes of agricultural and environmental soil investigation is not covered. NOTE？2？Guidance on soil sampling for these purposes including of contaminated or potentially contaminated sites is provided in the ISO？18400 series. ISO？18400-204 provides in addition guidance on sampling and measurement of soil (ground) gas. NOTE？3？The sampling methods, presented in this document may not be suitable for all types of soil e.g. peat with strong fibrous structure. NOTE？4？Some of the sampling methods presented in this document are suitable for both soil and rock. Water sampling for the purposes of quality control, quality characterisation and identification of sources of pollution of water, including bottom deposits and sludges, is not covered. NOTE？5？Water sampling for these purposes can be found in the ISO 5667 series.
