1.1 本指南涵盖了在岩土工程中使用发泡聚苯乙烯（EPS）土工泡沫的一些基本注意事项。 1.2 本指南提供了一系列信息，不建议采取行动。本指南不能取代教育或经验，应与专业判断结合使用。并非本指南的所有方面都适用于所有情况。 1.3 本指南无意代表或取代必须根据其判断特定专业服务是否充分的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本指南。 1.4 本指南标题中的“标准”一词仅表示本指南已通过ASTM国际共识程序获得批准。 1.5 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.6 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。 1.7 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 本指南告知用户在使用EPS土工泡沫时的设计注意事项，这有助于确定适用于岩土应用的适当EPS土工泡沫。 5.2 本指南不排除岩土工程设计专业人士的判断和实践。

1.1 This guide covers some of the basic considerations for the use of expanded polystyrene (EPS) geofoam in geotechnical projects. 1.2 This guide offers a collection of information and does not recommend a course of action. This guide 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. 1.3 This guide 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 guide be applied without consideration of a project’s many unique aspects. 1.4 The word “standard” in the title of this guide means only that this guide has been approved through the ASTM International consensus process. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.6 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. 1.7 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 This guide informs the user of design considerations in the use of EPS geofoam which assist in the determination of the appropriate EPS geofoam for geotechnical applications. 5.2 This guide does not preclude the judgment and practice of those competent in geotechnical design.
