标准摘要
[中文适用范围]： 本文件规定了在地面灌浆的锚栓上执行拉伸测试的规范，如 EN 1997-1 和 EN 1537 中所定义。 本文件认可三种测试方法。 测试方法1涉及循环拉伸载荷并测量载荷阶段的位移；测试方法 2 涉及循环拉伸载荷，并测量载荷阶段的载荷损失；测试方法3涉及分步加载并测量连续保持的张力载荷下的位移。 本文件规定了实验装置、测量仪器、测试程序、测试结果的定义和表示以及记录内容的规范。 注：本文件没有提供验证载荷大小和限制标准的规范。 这些方面包含在 EN 1997-1 或其 CEN 国家的国家附录中，以及 ISO 国家的该测试标准的类似国家应用文件中。 [外文原描述]： This document establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997-1 and EN 1537. Three methods of testing are recognized by this document. Test Method 1 involves cyclic tension loading with measurement of displacement at the load stages; Test Method 2 involves cyclic tension loading with measurement of load loss at the load stages; and Test Method 3 involves step-loading with measurement of displacement under successive maintained tension loads. This document provides specifications for the experimental devices, the measurement apparatus, the test procedures, the definition and presentation of the test results and the content of records. NOTE This document does not provide specification for the size of the proof load and the limiting criteria. These aspects reside in EN 1997-1 or its national annex for CEN countries and in similar national application documents for this test standard for ISO countries.
