1.1 本指南涵盖了在岩土工程和环境现场调查中分析、解释和建模区域化变量空间变化的建议。 1.2 本指南中讨论的空间变异度量包括变异函数和相关图；这些在参考文献中有详细描述。 ( 1- 4. ) . 2. 1.3 本指南旨在帮助那些已经熟悉本文讨论的地质统计学工具的人，但不提供有关空间变化分析、解释和建模的介绍性信息。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本指南提供了有组织的信息收集或一系列选项，并不推荐具体的行动方案。本文件不能取代教育或经验，应与专业判断一起使用。 并非本指南的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本文件。本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 无论是为了简单起见，还是由于缺乏信息，岩土工程师通常假设整个特定位置的土壤和岩石性质相同，即使他们意识到使用平均参数值可能会导致土壤参数与实际参数显著不同。 5.2 考虑到土壤和岩体特性的空间分布，应考虑在现场调查中使用地球静止学，因为它将根据可用的输入信息对土壤和岩石特性进行更准确的估计。 5.3 本指南旨在鼓励地质统计现场调查中空间变化的分析、解释和建模的一致性。 5.4 本指南应与指南一起使用 D5549 , D5923 和 D5924 .

1.1 This guide covers recommendations for analyzing, interpreting, and modeling spatial variation of regionalized variables in geotechnical and environmental site investigations. 1.2 The measures of spatial variation discussed in this guide include variograms and correlograms; these are fully described in Refs. ( 1- 4 ) . 2 1.3 This guide is intended to assist those who are already familiar with the geostatistical tools discussed herein and does not provide introductory information on the analysis, interpretation, and modeling of spatial variation. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Whether for the sake of simplicity or because of a lack of information, geotechnical engineers regularly assume that soil and rock properties are the same throughout a particular location, even though they realize that the use of averaged parameter values can result in soil parameters that are significantly different from the actual parameters. 5.2 Considering the spatial distribution of soil and rock mass properties, the use of geostatictics in site investigations should be considered as it will provide a more accurate estimation of the soil and rock properties based on the available input information. 5.3 This guide is intended to encourage consistency in the analysis, interpretation, and modeling of spatial variation in geostatistical site investigations. 5.4 This guide should be used in conjunction with Guides D5549 , D5923 , and D5924 .
