1.1 该试验方法用于确定土工合成材料层与加筋土挡土墙施工中使用的分段混凝土砌块单元之间的连接特性。该测试在用户确定的条件下进行，该条件以全尺寸再现连接系统。一系列试验的结果用于定义分段单元-土工合成材料连接系统的连接强度与法向荷载之间的关系。 1.2 这是一项性能测试，用于确定使用分段混凝土单元和土壤增强土工合成材料（土工织物或土工格栅）的挡土墙系统设计的性能。测试在连接的全尺寸结构上进行，并且可以在实验室或现场进行。 1.3 以SI单位表示的值被视为标准。以英寸-磅单位表示的值仅供参考。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.5 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 土工合成材料与分段混凝土砌块单元之间的连接强度用于加筋土挡土墙的设计。5.2 该试验用于确定加筋土挡土墙中由分段混凝土砌块单元和土工合成材料加筋层形成的连接系统的设计的连接强度。在不同的法向载荷下进行一系列这些连接测试允许建立连接强度和法向载荷之间的关系。该关系可以是线性、双线性或一些其他复杂的数学表达式。 5.3 该连接强度测试是性能测试（实验室或现场）；因此，应使用全尺寸系统组件进行。测试条件由用户选择，不用于常规测试。 5.4 作为对全尺寸系统组件的性能测试，它考虑了这些类型的挡土墙系统通常存在的施工程序和材料公差中的一些变量。

1.1 This test method is used to determine the connection properties between a layer of geosynthetic reinforcement and segmental concrete block units used in construction of reinforced soil retaining walls. The test is carried out under conditions determined by the user that reproduce the connection system at full scale. The results of a series of tests are used to define a relationship between connection strength for a segmental unit-geosynthetic connection system and normal load. 1.2 This is a performance test used to determine properties for design of retaining wall systems utilizing segmental concrete units and soil reinforcing geosynthetics, either geotextiles or geogrids. The test is performed on a full-scale construction of the connection and may be run in a laboratory or the field. 1.3 The values stated in SI units are regarded as the standard. The values stated in inch-pound units are provided for information only. 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 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 The connection strength between geosynthetic reinforcement and segmental concrete block units is used in design of reinforced soil retaining walls. 5.2 This test is used to determine the connection strength for the design of the connection system formed by segmental concrete block units and geosynthetic reinforcement layers in reinforced soil retaining walls. Performing a series of these connection tests at varying normal loads permits development of a relationship between connection strength and normal load. This relationship may be linear, bilinear, or some other complex mathematical expression. 5.3 This connection strength test is meant to be a performance test (laboratory or field); therefore, it should be conducted using full-scale system components. The conditions for the test are selected by the user and are not for routine testing. 5.4 As a performance test on full-scale system components, it accounts for some of the variables in construction procedures and materials tolerance normally present for these types of retaining wall systems.
